The HVAC high temperature alarm was going off when we arrived this morning. Decreased the temperature set point on the HVAC to 66°F at 08:22. Temperature continued to increase. Decreased the temperature set point to 65°F at 09:28. Learned from ISU maintenance that there was an issue with frozen pipes and a subsequent malfunction in the building's heating and cooling system that was causing our HVAC system to compete with the building system to maintain temperatures. It is also possible that the AC unit outside was frozen. (Local temperatures were approximately -10°F this morning.) Increased temperature set point to 67°F at 11:33 and opened the garage door in the upper area outside the cleanroom to prevent HVAC system from overwork and decrease temperatures. Temperatures decreased and came within specifications for the remainder of the work day. Stringing work was halted from 07:30 to 11:30.

Sector 1 - DAQ Scintillator timing information now working (Ch. 96, 99, 104, 105, 106, 107)

Quad coincidence in all AND mode close to working, need to get a delay box for one channel so that the cable delay from the other three is compensated for on the one channel that is "faster" by 40 ns.

Drift chamber isn't putting out a normal signal to the pre-amp that's normal for gammas. Unknown what is causing this problem at the moment, may be an issue with our current triggering setup on the scope.

Sector 5 - Restringing and testing wires in SL1 that were out of spec. Rotated and aligned chamber for stringing repairs in SL2.

=01/03/13=

Cleanroom temperatures drifted out of spec this morning. Opened the garage door in the upper area to bring in colder air. Temperatures came back within specifications for the remainder of the day.

Sector 1 - Found that the HV supply board was not providing voltage to the Field wires. Began troubleshooting this issue.

Sector 5 - Restringing and testing wires in SL2 that were out of spec. Completed weekly Tension Trend test.

==12/3/12 Meeting Notes with Mac and George at ISU==

===Construction Proceedures:===

Chambers outside cleanroom should have covers to keep dust off buss wires

Cap 113 (Brown one) needs to be replaced on STB board.

Need 2 amp fuse on 5 Volt supply to pre-amps.

operate chamber STB voltage at 6 Volts

Chamber grounding (ground through HV cable)

===Chamber operating procedures===

1.) post amplifier in VME crate had 150 mV peak-peak noise

2.) Stop using the current ADB crate

3.) New nominal Voltages from Mac are

S:F:G = 1300:-650:

S/F = 2

S/G = 5/7

Signal output doubles every 75 Volts difference between sense and field

4.) Discriminator level for signals:

5.) Need to lower the HV trip current back to 1 microA. May increase it to 5 micro Amps when burning in.

6.) Change trip speed to 0.1 sec

===ISU Tasks:===

1.) Install cover on top of chamber, top could be made from home insulation sheets that has been covered with paper or plastic sheeting.

2.) Install 208 Volts for ADB crates that will be sent by JLab to replace the one they have given us.

3.) solder jumpers onto HV boards, install them in January when George returns

4.) Mylar window on S1 chamber needs to have some tape and weather stripping redone or modified

5.) Get allen head 3/32 for torque wrench, remember to replace brass screws if they are removed for some reason

6.) do not do final instrumentation, purge covers, and dust covers on the last 2 chambers until checking with JLab, the may want to survey them after delivery

===JLab Tasks===

1.) What are the fault conditions on the STB board when the power supply exceeds voltage/current

2.) Need signal cables with strain relief connects that have the shielding wrap grounded on the STB board but not grounded on the DAQ cabinet

3.) George will send purge covers and come back in January to install

=12/3/12=

Sector 1 - Summary of Results:

- ADB continues to have problems with noise, and today we were unable to get it to
reliably show a cosmic pulse. Switched to just using the post-amp for now.
Removed the grounding strap from the S1 Chamber. No noticeable difference in noise
levels.

- During cosmic pulse counting, Mac determined the new nominal voltage for sense wires
should be 1400V to avoid a saturation condition that results in a large characteristic pulse
consistently showing up.

- Mac also suggested we start keeping a log of current levels whenever running HV
testing, and ensure the over-current trip settings are correct on the HV power supply (0.1
sec, 1μA)

- J-lab should be sending us some new equipment to serve the role of the ADB crate -
either a new ADB or some DCRB's.

Sector 5 - strung 51 Sense wires (now on SL1 - row 200).

Sector 6 - tested SL2 through row 154. The decision was made with Mac, George, Dr. Forest and Dr. McNulty that post-potting testing will not continue after today. The post-potting Tension Trend data will be compared with pre-potting Tension Trend data to check for any unexpected results.

=12/4/12=

We only had two stringers today, so we focused on finishing the Sense wire stringing in Sector 5.

Sector 5 - strung 81 Sense wires. All stringing now complete. Will begin visual inspection and final pre-potting testing tomorrow.

=12/5/12=

Sector 1 - Dr. Forest and David continued testing. The following is from David's report on today's progress:

"Pulse Generator seems to be functioning right now.

Proceeded to gather counting efficiency data for various HV settings on the wires. Discovered
that during ramp-up the sense wires exceeded the 1µA safety cut-off. Raised the cut-off to 3 µA
and the sense wires were able to ramp-up to 1400V without the safety tripping. Current stabilized
at 0.115 µA on sense, 0.190 µA on field, and 0.000 µA on guards after ramp-up.

A significant amount of noise is generated in the post-amp signal after turning on the DC power
supply for the STB, peak to peak amplitude averages around 50 mV. Turned up the
discriminator's threshold to 100 mV for an initial test run. Experimenting with the trigger level
on the oscilloscope, I found that 75 mV is a "safe" level to use for triggering only on cosmic
pulses and not on noise. Even at the 75 mV threshold, there are occasional noise pulses that
exceed that level and cause false counts (pulse does not conform to what a normal cosmic looks
like). Consulted with Dr. Forest, he thinks a couple of the noise pulses we're seeing are from the
HVAC system (confirmed this by turning off the HV, and noise pulses still came through the
post-amp), and some others may be spark discharges on the ground-line from other equipment in
the building. He suggested running longer count times (10+ min.) to make the noise pulses a
negligible part of the count.

I took counts running from 600-1,000 sec at a few different voltage settings, and we got results
that are in line with what you'd expect - upping the voltage results in a higher count rate. I
already took one background sampling for 50 minutes over lunch break, and we are taking
another overnight to get a larger sample of background while no one is likely to be working in
the building in other labs." (David Coneff 12/5/12).

Sector 5 - tested Sense wires strung on Tuesday (row 200-226). Began visual inspection. Began SL2 Field pre-potting testing. Tested row 2-40 (267 Field wires).

Completed mylar window installation supply inventory for Sectors 2,3,5 and 6. Will compile notes and e-mail George a final list of supplies we have and need.

=12/6/12=

Sector 5 - pre-potting testing SL2 Fields row 41-184 (1008 Field wires). Completed weekly Tension Trend test.

Completed weekly cleanroom clean.

=12/10/12=

Sector 1 - soldered jumpers on 7 SL1 HV boards.

Sector 5 - pre-potting testing SL2 Fields row 185-204 and SL1 Fields row 185-191 (189 total wires).

=12/11/12=

Sector 1 - continued testing high voltage plateau and confirmed multiple hits using the ADB crate.

Sector 5 - pre-potting testing - completed SL2 Fields. Tested SL1 Fields row 3-48. (483 total wires).

Received our particle counter from Kanomax after calibration. Particle readings from this afternoon on will be taken with our counter.

=12/12/12=

Sector 1 - soldered jumpers on 5 HV boards.

David continued testing. DAQ is now setup with the post-amp and discriminators to function on 16 channels. Threshold for
discriminators is now set to a nominal -1.0 V to eliminate noise (HVAC system, grounding noise, etc.). Double counts are still
occasionally happening on a given channel even with the higher threshold. Determined the DAQ can handle up to a 12 KHz event rate.
Started testing all 16 channels to confirm signal injection works reliably with the DAQ

Sector 5 - pre-potting testing SL1 Fields row 49-114 (462 total wires).

=12/13/12=

Sector 1 - Soldered jumpers on 3 HV boards. Began setting up scintillators to begin coincidence counting of cosmic rays.

Sector 5 - pre-potting testing Sl1 Fields row 115-197 (531 total wires). Completed weekly Tension Trend test.

Completed weekly cleanroom clean.

=12/17/12=

Sector 5 - pre-potting testing SL2 Sense row 3-80 and SL1 Sense row 3-70 (432 total wires).

=12/18/12=

Sector 5 - pre-potting testing SL2 Sense row 81-226 and SL1 Sense row 71-226 (906 total wires).

=12/19/12=

High temperature alarm. Decreased temperature set point on HVAC by one degree. Temperatures are now within stringing specifications.

Sector 5 - visual inspection and replacement of wires that are out of specifications.

Lewimar3: /* 11/29/12 */

=11/1/12=

Sector 5 - strung 51 Sense wires (now on SL2 - row 176). Completed weekly Tension Trend test.

Sector 6 - Finished potting top plate (both SL1 and SL2).

Completed weekly cleanroom clean.

=11/5/12=

Visual inspection of the top plate potting on Sector 6 showed some feed throughs where epoxy retracted during hardening. Inspected entire top plate for bubbles, exposed bottom cups on feed throughs and other potential issues. Determined that a possible explanation is that this scale does not have the appropriate resolution for mixing small batches of epoxy (low total weight for the batch). We did not see this problem when potting Sector 1, however, much larger batches of epoxy were mixed then because the directive from the former manager was to fill the entire feed through cup with epoxy and more epoxy was required overall. The current potting procedure states that only the lower feed through cup is to be filled with glue. Another scale has been ordered and shipping has been expedited. In the mean time, larger batches of epoxy are being mixed to improve gram to gram ratio of chemicals. Additional epoxy was added to deficient feed throughs using epoxy mixed in larger total weight batches. Visual inspection will be completed tomorrow before proceeding.

No stringing was completed on Sector 5 because both lifts were used to either pot or inspect Sector 6.

Re-routed the nitrogen gas supply lines for more efficient and easy use during potting. Repaired inappropriately installed nitrogen gas lines to potting machines.

Re-covered two rollers from the Sector 5 stringing machine with the new foam material Steve sent from J-Lab.

Sent copies of the Sense spreadsheets to George. There was a problem in entering the "calculated period" into the "measured period" column. Doing so returned a 10% tension error. In the Field spreadsheets, the same course of action yields a 0% tension error. It was found, and George confirmed, that the problem was that the "design tension load" in the Specs sheet has 20g instead of 18.2g as indicated in the stringing manual. The ISU Sense wire spreadsheets will be changed accordingly.

=11/6/12=

Sector 5 - strung 60 Sense wires (now on SL2 - row 196).

Sector 6 - visual inspection of Monday potting. All looks good.

We were short handed today, so we tried to make up some stringing time on Sector 5 with the two stringers working today.

=11/7/12=

Sector 1 - per Dr. Forest's request, continuity checked all new cables. All check out fine. Began design for scintillator platform.

Sector 5 - strung 39 Sense wires (now on SL2 - row 209). Had some issues with Sense wire breaking during stringing. Replaced rollers on stringing machine with rollers covered in the new foam sent from J-Lab. These rollers seem to be working much better.

Sector 6 - installed and glued all plugs in top plate holes. Should be set to rotate and begin potting the bottom plate late tomorrow morning.

=11/8/12=

Sector 1 - testing ECL output from ADB with new cables.

Sector 5 - strung 54 Sense wires (finished SL2 Sense stringing). Completed weekly Tension Trend test.

Sector 6 - rotated and leveled chamber for potting bottom plate. Potted SL2 row 228-212.

Completed weekly cleanroom clean.

=11/12/12=

Sector 5 - completed a brief visual inspection of SL2 wires. Rotated and aligned chamber for SL1 stringing. Strung 46 Sense wires (now on SL1 - row 19).

Sector 6 - potted SL2 row 211-93.

=11/13/12=

Sector 5 - strung 60 Sense wires (now on SL1 - row 39).

Sector 6 - potted SL2 row 22-92.

Our particle counter was sent to Kanomax for calibration. All readings taken from today on will be with a loaner counter of the same model. Kanomax reported that the calibration would take 7 to 10 business days.

=11/14/12=

Sector 5 - strung 63 Sense wires (now on SL1 - row 60).

Sector 6 - finished potting SL2. Potted rows 1-120 and 158-228.

=11/15/12=

Sector 5 - strung 51 Sense wires (now on SL1 - row 77). Completed weekly Tension Trend test.

Sector 6 - finished potting SL1. Began visual inspection of bottom plate potting.

Completed weekly cleanroom clean.

=11/19/12=

Sector 1 - Summary of results:

- Cross-talk across ECL channels is resolved by clamping additional
grounded shielding on HVTB->ADB cables.

- 15 out of 16 channels currently connected show hits on the DAQ when
injecting signal on the respective wire in Sector 1. ADB Ch. 1 - DAQ
Ch. 16 doesn't show any hits. May be an issue with the threshold for
triggering the ECL on the ADB crate. Dr. Forest suggested tweaking the
threshold as a troubleshooting step for tomorrow.

- One channel tested today had an unusually shaped pulse on the ADB
Analog-out, but the DAQ still recorded hits. May just be an anomaly of
the ADB crate.

Sector 5 - strung 63 Sense wires (now on SL1 - row 98).

Sector 6 - added a small amount of epoxy to a few feed throughs that appeared to be scant.

=11/20/12=

Sector 1 - ran signal and power cables for scintillators.

Sector 5 - strung 51 Sense wires (now on SL1 - row 115). Completed weekly Tension Trend test because we will be off for the holiday for the rest of the week. Having repeated issues with the stringing machine breaking the Sense wire after it has been extended into the chamber. The problem appears to be in the right pulley. Will trouble shoot next week and consider switching out the stringing machine for the one from Sector 6.

Sector 6 - rotated back to the top plate and completed a final visual inspection of potting. Added a small amount of epoxy to several feed throughs that appeared to be scant.

=11/27/12=

Sector 1 - went shopping for supplies and began construction of table system for scintillators.

Sector 5 - strung 51 Sense wires (now on SL1 - row 132).

Sector 6 - rotated chamber to prepare for final testing before mylar installation.

=11/28/12=

Sector 1 - began construction of scintillator support system.

Sector 5 - strung 51 Sense wires (now on SL1 - row 149). Replaced stringing machine with the one from Sector 6. The machine was causing curling and breaking with the Sense wire. Steve said he'd send us a backup machine from JLab.

=11/29/12=

Sector 1 - completed construction of scintillator support system.

Sector 5 - strung 51 Sense wires (now on SL1 - row 166).

Sector 6 - began final tension testing. Tested SL2 Fields row 2-25.

Marcie received training from George on mylar cover construction for HVB and STB. Stringers and Marcie received training on soldering jumpers to HVB.

[[File:Scintillator_Table_II.jpg || 200 px]]

=11/30/12=

Sector 1 - trouble shooting noise issues with Mac and George.

Sector 5 - strung 51 Sense wires now on SL1 - row 183). Completed weekly Tension Trend test.

Sector 6 - final tension testing SL2 Fields row 26-40. Completed weekly Tension Trend test.

It was found, and George confirmed, that the problem was that the "design tension load" in the Specs sheet has 20g instead of 18.2g as indicated in the stringing manual. The ISU Sense wire spreadsheets will be changed accordingly.

Sector 5 - strung 60 Sense wires (now on SL2 - row 196).

Sector 6 - visual inspection of Monday potting. All looks good.

We were short handed today, so we tried to make up some stringing time on Sector 5 with the two stringers working today.

=11/7/12=

Sector 1 - per Dr. Forest's request, continuity checked all new cables. All check out fine. Began design for scintillator platform.

Sector 5 - strung 39 Sense wires (now on SL2 - row 209). Had some issues with Sense wire breaking during stringing. Replaced rollers on stringing machine with rollers covered in the new foam sent from J-Lab. These rollers seem to be working much better.

Sector 6 - installed and glued all plugs in top plate holes. Should be set to rotate and begin potting the bottom plate late tomorrow morning.

=11/8/12=

Sector 1 - testing ECL output from ADB with new cables.

Sector 5 - strung 54 Sense wires (finished SL2 Sense stringing). Completed weekly Tension Trend test.

Sector 6 - rotated and leveled chamber for potting bottom plate. Potted SL2 row 228-212.

Completed weekly cleanroom clean.

=11/12/12=

Sector 5 - completed a brief visual inspection of SL2 wires. Rotated and aligned chamber for SL1 stringing. Strung 46 Sense wires (now on SL1 - row 19).

Sector 6 - potted SL2 row 211-93.

=11/13/12=

Sector 5 - strung 60 Sense wires (now on SL1 - row 39).

Sector 6 - potted SL2 row 22-92.

Our particle counter was sent to Kanomax for calibration. All readings taken from today on will be with a loaner counter of the same model. Kanomax reported that the calibration would take 7 to 10 business days.

=11/14/12=

Sector 5 - strung 63 Sense wires (now on SL1 - row 60).

Sector 6 - finished potting SL2. Potted rows 1-120 and 158-228.

=11/15/12=

Sector 5 - strung 51 Sense wires (now on SL1 - row 77). Completed weekly Tension Trend test.

Sector 6 - finished potting SL1. Began visual inspection of bottom plate potting.

Completed weekly cleanroom clean.

=11/19/12=

Sector 1 - Summary of results:

- Cross-talk across ECL channels is resolved by clamping additional
grounded shielding on HVTB->ADB cables.

- 15 out of 16 channels currently connected show hits on the DAQ when
injecting signal on the respective wire in Sector 1. ADB Ch. 1 - DAQ
Ch. 16 doesn't show any hits. May be an issue with the threshold for
triggering the ECL on the ADB crate. Dr. Forest suggested tweaking the
threshold as a troubleshooting step for tomorrow.

- One channel tested today had an unusually shaped pulse on the ADB
Analog-out, but the DAQ still recorded hits. May just be an anomaly of
the ADB crate.

Sector 5 - strung 63 Sense wires (now on SL1 - row 98).

Sector 6 - added a small amount of epoxy to a few feed throughs that appeared to be scant.

=11/20/12=

Sector 1 - ran signal and power cables for scintillators.

Sector 5 - strung 51 Sense wires (now on SL1 - row 115). Completed weekly Tension Trend test because we will be off for the holiday for the rest of the week. Having repeated issues with the stringing machine breaking the Sense wire after it has been extended into the chamber. The problem appears to be in the right pulley. Will trouble shoot next week and consider switching out the stringing machine for the one from Sector 6.

Sector 6 - rotated back to the top plate and completed a final visual inspection of potting. Added a small amount of epoxy to several feed throughs that appeared to be scant.

=11/27/12=

Sector 1 - went shopping for supplies and began construction of table system for scintillators.

Sector 5 - strung 51 Sense wires (now on SL1 - row 132).

Sector 6 - rotated chamber to prepare for final testing before mylar installation.

=11/28/12=

Sector 1 - began construction of scintillator support system.

Sector 5 - strung 51 Sense wires (now on SL1 - row 149). Replaced stringing machine with the one from Sector 6. The machine was causing curling and breaking with the Sense wire. Steve said he'd send us a backup machine from JLab.

=11/29/12=

Sector 1 - completed construction of scintillator support system.

Sector 5 - strung 51 Sense wires (now on SL1 - row 166).

Sector 6 - began final tension testing. Tested SL2 row 2-25.

Marcie received training from George on mylar cover construction for HVB and STB. Stringers and Marcie received training on soldering jumpers to HVB.

Sector 5 - strung 51 Sense wires (now on SL2 - row 176). Completed weekly Tension Trend test.

Sector 6 - Finished potting top plate (both SL1 and SL2).

Completed weekly cleanroom clean.

=11/5/12=

Visual inspection of the top plate potting on Sector 6 showed some feed throughs where epoxy retracted during hardening. Inspected entire top plate for bubbles, exposed bottom cups on feed throughs and other potential issues. Determined that a possible explanation is that this scale does not have the appropriate resolution for mixing small batches of epoxy (low total weight for the batch). We did not see this problem when potting Sector 1, however, much larger batches of epoxy were mixed then because the directive from the former manager was to fill the entire feed through cup with epoxy and more epoxy was required overall. The current potting procedure states that only the lower feed through cup is to be filled with glue. Another scale has been ordered and shipping has been expedited. In the mean time, larger batches of epoxy are being mixed to improve gram to gram ratio of chemicals. Additional epoxy was added to deficient feed throughs using epoxy mixed in larger total weight batches. Visual inspection will be completed tomorrow before proceeding.

No stringing was completed on Sector 5 because both lifts were used to either pot or inspect Sector 6.

Re-routed the nitrogen gas supply lines for more efficient and easy use during potting. Repaired inappropriately installed nitrogen gas lines to potting machines.

4 ingredients to contract

1.) MOU: Memorandum of Understanding,

2.) SOW: Statement of Work

3.) Detailed Schedule

4.) Sole Source Justification

5.) Contact person: Pre Award Dave Harris? Approve Terms and conditions

University gets a Purchase Req: covers SOW, Terms & Condition, & Schedule.

We respond with proposal containing exceptions and work plan. 1 team of 2 stringers can do a wire in 6 minutes. Stringers spend 1/2 of their time stringing the rest of time preparing , Q&A, ... JLab expects a crew of 5 people. If we think we can't make the schedule we need to ask for more people. Stringers hourly rate ($30-$35/hr with overhead and benefits). Lead stringer is +$5/hr more.

Then they respond with contract.

"Cost Reimbursable" contract, University not liable if we go over budget

Can we survey to 50 microns? No. 200 microns.

Dimensions of door from loading dock to clean room
65" wide
90" high

The doors into and out of the different areas will be 9'8" high in order to help facilitate the transport of equipment into and out of the different areas of the clean room.

The desks in the clean room will act as a table top area to place tools and other equipment currently in use during the construction of the wire chambers. Also, they will serve as a place to perform any calculations or other miscellaneous work that may come up while construction is ongoing.

The cabinets on the other side of the room will be a permanent storage area for all tools and equipment not currently in use at the two work stations.

The path in between the workstations and the cabinets will be kept clear of all obstructions in order facilitate the movement of equipment into and out of the room as needed.

The two workstations will be where the wire chambers are constructed. The workstations will have a standing/sitting apparatus built around them in order to help those who are stringing the wire chambers to have better access to the chambers from above. Schematics for these will be uploaded as they are designed.

The heavy equipment storage area will be where all the heavier equipment (i.e. dollies, fabrication materials, etc...) that will not fit, or does not need to be stored in the individual work station cabinets will be kept.

The HEPA filters will cover roughly ~10-12% of the ceiling in order to maintain a Class 10,000 environment. The filters will move approximately 35-40 air volumes per hour.

Overhead lighting will be suspended from the frame in order to provide sufficient lighting for the room occupants to work within.

==Environmental control needed==

Temperature control constraint is <math>\pm 2\% :\frac{7\% \;\;change\;\;in \;\;tension}{6 \;\;Degree \;\; Farenheit}</math>

The wire tension can fluctuate no more than 5% from the mean wire tension specification.

This means that the temperature should be controlled to within +/- 2 Degrees Ferenheit

Humidity control: 55 % or less

===HVAC performance June 2011===

The HVAC system has been repaired. It was set to a temperature of 66 +/- 2 degree F. I saw the cooling light turn on at least once. On June 21,2011 the set point was changed from 66 to 72.

[[File:HVAC_4weekTempStability_4-11.png| 200 px]]

Below is a snapshot after I turned the set point from 66 to 72.
It looks like the cycle time was about 20 minutes when set to 66 degrees and 2 degree stability.

[[File:HVAC_Heating_4-21-11.png | 200 px]]

The temperatures measured after changing the temperature set point to 72.

[[File:HVAC_Heating_4-22-11.png | 200 px]]

Temperature Oscillations observed before adding a tarp over the large doorway

[[File:HVAC_Oscilation_4-22-11.png | 200 px]]

Some IAC personnel moved the tarp for a little while at time index 18:40. Fortunately there will be 2 doors put in. One where the tarp is now and another 5 feet towards the basement exit. Otherwise, I would worry about the impact of opening the large door on stringing.

[[File:HVAC_TarpOpened_4-22-11.png | 200 px]]

The temperature seems to be more stable now with the tarp over the doorway, allowing the HVAC to control the temperature in only the clean room area. Below is a graph of the temperature in the room over a 6 hour period starting at 8 am until 2 pm on June 24, 2011.

[[File:HVAC_WithTarp_4-23-11.png | 200 px]]

Below is a plot of the temperatures recorded over the last 7 days (4/18 - 24 / 11) when all the changes were happening to try and bring the temperature up to 72 degrees.

[[File:HVAC_TempLog_4-28-24-11.png | 200 px]]

Below is a plot of the temperatures recorded over the last 7 days (4/21 - 27 / 11) . There appears to be a slow rise?

[[File:HVAC_TempLog_4-27-11.png | 200 px]]

;6/28/11

I went down to the clean room and and saw that the Duct work was started. There are open holes into the adjacent room right now which need to be closed up.

;I also saw that the set point has been raise to 73 degrees. This explains the temperature rise above.

;8/11/11

Began moving the temperature sensors to new locations in the clean room. We plan on mounting them at locations which will measure the stringing temperature at the top and bottom of a chamber while we are stringing the chamber

[[File:HVAC_TempLog_8-12-11.png | 200 px]]

;8/24/11

Installed an air deflector on the 5th vent furthest from the HVAC unit at approximately 11:30 AM, fourth vent furthest at ~3:00 PM, and 3rd vent at 3:15 PM.

=== July 2011 HVAC performance===

6/6/11

Construction begins in the clean room. I opened the tarp over our big door a little bit and now I see temperature oscillations again.

[[File:HVAC_TempLog_6-6-11.png | 200 px]]

6/7/11

The first few days of July were stable but there was a positive temperature gradient slowly increasing the temperature about +1/3 degree F per day. Then on July 4 something caused temperatures to fluctuate at least 1 degree within a day. Could it be that the university turned off the AC over the weekend and there was a delay seeing the building aclimate?

4 ingredients to contract

1.) MOU: Memorandum of Understanding,

2.) SOW: Statement of Work

3.) Detailed Schedule

4.) Sole Source Justification

5.) Contact person: Pre Award Dave Harris? Approve Terms and conditions

University gets a Purchase Req: covers SOW, Terms & Condition, & Schedule.

We respond with proposal containing exceptions and work plan. 1 team of 2 stringers can do a wire in 6 minutes. Stringers spend 1/2 of their time stringing the rest of time preparing , Q&A, ... JLab expects a crew of 5 people. If we think we can't make the schedule we need to ask for more people. Stringers hourly rate ($30-$35/hr with overhead and benefits). Lead stringer is +$5/hr more.

Then they respond with contract.

"Cost Reimbursable" contract, University not liable if we go over budget

Can we survey to 50 microns? No. 200 microns.

Dimensions of door from loading dock to clean room
65" wide
90" high

The doors into and out of the different areas will be 9'8" high in order to help facilitate the transport of equipment into and out of the different areas of the clean room.

The desks in the clean room will act as a table top area to place tools and other equipment currently in use during the construction of the wire chambers. Also, they will serve as a place to perform any calculations or other miscellaneous work that may come up while construction is ongoing.

The cabinets on the other side of the room will be a permanent storage area for all tools and equipment not currently in use at the two work stations.

The path in between the workstations and the cabinets will be kept clear of all obstructions in order facilitate the movement of equipment into and out of the room as needed.

The two workstations will be where the wire chambers are constructed. The workstations will have a standing/sitting apparatus built around them in order to help those who are stringing the wire chambers to have better access to the chambers from above. Schematics for these will be uploaded as they are designed.

The heavy equipment storage area will be where all the heavier equipment (i.e. dollies, fabrication materials, etc...) that will not fit, or does not need to be stored in the individual work station cabinets will be kept.

The HEPA filters will cover roughly ~10-12% of the ceiling in order to maintain a Class 10,000 environment. The filters will move approximately 35-40 air volumes per hour.

Overhead lighting will be suspended from the frame in order to provide sufficient lighting for the room occupants to work within.

==Pictures of Path from Dock to clean room==

As measured on the spit in the JLab clean room on April 28, 2011. The narrowest part of the R1 detector was 78". A door should accomodate 78" + box.

The Tip of the stringing fixture was 13' 5" high from the floor.

Below are pictures showing how our R1 mock up, an equilateral triangle 8' on the side, passes from the loading dock to the clean room area.

==Environmental control needed==

Temperature control constraint is <math>\pm 2\% :\frac{7\% \;\;change\;\;in \;\;tension}{6 \;\;Degree \;\; Farenheit}</math>

The wire tension can fluctuate no more than 5% from the mean wire tension specification.

This means that the temperature should be controlled to within +/- 2 Degrees Ferenheit

Humidity control: 55 % or less

===HVAC performance June 2011===

The HVAC system has been repaired. It was set to a temperature of 66 +/- 2 degree F. I saw the cooling light turn on at least once. On June 21,2011 the set point was changed from 66 to 72.

[[File:HVAC_4weekTempStability_4-11.png| 200 px]]

Below is a snapshot after I turned the set point from 66 to 72.
It looks like the cycle time was about 20 minutes when set to 66 degrees and 2 degree stability.

[[File:HVAC_Heating_4-21-11.png | 200 px]]

The temperatures measured after changing the temperature set point to 72.

[[File:HVAC_Heating_4-22-11.png | 200 px]]

Temperature Oscillations observed before adding a tarp over the large doorway

[[File:HVAC_Oscilation_4-22-11.png | 200 px]]

Some IAC personnel moved the tarp for a little while at time index 18:40. Fortunately there will be 2 doors put in. One where the tarp is now and another 5 feet towards the basement exit. Otherwise, I would worry about the impact of opening the large door on stringing.

[[File:HVAC_TarpOpened_4-22-11.png | 200 px]]

The temperature seems to be more stable now with the tarp over the doorway, allowing the HVAC to control the temperature in only the clean room area. Below is a graph of the temperature in the room over a 6 hour period starting at 8 am until 2 pm on June 24, 2011.

[[File:HVAC_WithTarp_4-23-11.png | 200 px]]

Below is a plot of the temperatures recorded over the last 7 days (4/18 - 24 / 11) when all the changes were happening to try and bring the temperature up to 72 degrees.

[[File:HVAC_TempLog_4-28-24-11.png | 200 px]]

Below is a plot of the temperatures recorded over the last 7 days (4/21 - 27 / 11) . There appears to be a slow rise?

[[File:HVAC_TempLog_4-27-11.png | 200 px]]

;6/28/11

I went down to the clean room and and saw that the Duct work was started. There are open holes into the adjacent room right now which need to be closed up.

;I also saw that the set point has been raise to 73 degrees. This explains the temperature rise above.

;8/11/11

Began moving the temperature sensors to new locations in the clean room. We plan on mounting them at locations which will measure the stringing temperature at the top and bottom of a chamber while we are stringing the chamber

[[File:HVAC_TempLog_8-12-11.png | 200 px]]

;8/24/11

Installed an air deflector on the 5th vent furthest from the HVAC unit at approximately 11:30 AM, fourth vent furthest at ~3:00 PM, and 3rd vent at 3:15 PM.

=== July 2011 HVAC performance===

6/6/11

Construction begins in the clean room. I opened the tarp over our big door a little bit and now I see temperature oscillations again.

[[File:HVAC_TempLog_6-6-11.png | 200 px]]

6/7/11

The first few days of July were stable but there was a positive temperature gradient slowly increasing the temperature about +1/3 degree F per day. Then on July 4 something caused temperatures to fluctuate at least 1 degree within a day. Could it be that the university turned off the AC over the weekend and there was a delay seeing the building aclimate?

The formula is from Physics 10X but more importantly it contains wire parameters useful for the calculation

==Discussion items==

1.) Budget

*JLab to ISU travel for JLab personnel to inspect operations
* shipping container for R1 chambers

2.) Clean room

cost =

assume we copy the ODU clean room

Using IAC conference room space, need to remove carpet and paint floor.

3.) hiring timeline

9/08 NSF proposal submission

4.) stringing platform and DC stringing support arm

5.) Manpower

6.) MOU to support post doc request or faculty release time

7.) Stringing equipment

a.) crimping tool

b.) glue

c.) wire or feedthroughs?

d.) wire tension measurement (PC, Magnets, associated electronics

A few pictures ff the R1 full size proto type from my JLab visit on 9/16/07. It is about 6 feet tall.

==Construction First R1 Chamber at JLab==

As measured on the spit in the JLab clean room on April 28, 2011. The narrowest part of the R1 detector was 78". A door should accomodate 78" + box.

The Tip of the stringing fixture was 13' 5" high from the floor.

=10/01/12=

Sector 1 - began training stringers to turn on high voltage and look for signals using STB probe and ADB monitoring system.

Sector 5 - restrung Guard and Field wires for replaced feed throughs in SL1 (Fields: 167-11, 187-2, 223-8 and 225-11. Guards: 227-10 and 228-3). All wires strung were continuity tested for potential crossed wires.

Sector 6 - tested SL2 Field wires from row 134 to 168 (245 wires).

=10/02/12=

Sector 1 - Injected a 10 MHz square wave with a 40 mV peak-peak amplitude into each channel of the ADB monitor system. Tested the gain on A and B of each channel. Preliminary results show 5 channels that may not be functioning properly.

Sector 5 - removed and replaced 4 more damaged or glue contaminated feed throughs that were found during visual inspection (SL1: 16-2 (Sense). SL2: 37-1 (Guard), 227-8 (Field) and 227-9 (Field)).

Sector 6 - tested SL2 Field wires from row 169 to 189 (147 wires).

Temperatures in the cleanroom have been decreasing slowly over the last week. Increased the temperature set point of the HVAC system by one degree to keep temperatures within cleanroom specifications. Will monitor and report any issues.

=10/03/12=

Sector 1 - Injected a 1kHz -40mV peak pulse with a 0.1% duty cycle directly into the ADB monitor system to verify ECL output for all 96 channels. All channels confirmed a -1V peak with a 1us pulse width. Mapped Layer/Wire to corresponding ADB channel. The map that was sent to us does not correspond between ADB channel and Layer/Wire.

Sector 6 - tested Field wires from row 190 to 227 (263 wires).

=10/04/12=

Sector 1 - Spent considerable time trouble shooting ribbon cables to verify that an injected signal maps correctly from each STB channel to each ADB channel and produces an ECL output.

Sector 5 - completed weekly Tension Trend test.

Sector 6 - completed weekly Tension Trend test. Tested SL2 Sense wires from row 3 to 39 (109 wires).

Completed weekly clean in cleanroom.

=10/08/12=

Sector 1 - reorganized rack to accommodate for the VME crate.

Sector 5 - rotated chamber; repositioned magnet; leveled the stringing arm and aligned the chamber for Sense wire stringing in SL2.

Sector 6 - tested SL2 Sense wires from row 40-146 (321 wires).

=10/09/12=

Sector 1 - continuity tested all STB to ADB cables. R1SC4 and R1SC6 appear to be the only completely functioning cables.

Sector 5 - finished removing debris from SL2.

Sector 6 - rotated chamber; repositioned magnet and leveled stringing arm. Will align the chamber for SL2 stringing tomorrow.

=10/10/12=

Sector 1 - DC tested STB to ADB cables to check to see if replacing end connectors would fix the 4 bad cables.

Sector 5 - continuity tested all remaining Field wires. Removed a few more pieces of metal debris that were found inside the chamber.

Sector 6 - aligned the chamber for SL2 wire replacement for feed throughs that were removed and replaced. Replaced and tested wires and began final visual inspection before potting begins next week.

=10/11/12=

Sector 1 - worked on replacing connector ends on STB to ADB cable.

Sector 5 - restrung Field and Guard wires from replaced feed throughs (SL2: 227-8F, 227-9F, 37-1G, 228-3G). Completed weekly Tension Trend test.

Sector 6 - completed weekly Tension Trend test. Confirmed tension values for 3 wires that show inconsistent behavior in the Tension Trend (SL1: 90-2S. SL2: 20-7F, 60-7F). All three have a crimp pin that was easily moved in the feed through. Crimp pins were seated well and final tension measurements were taken. All are within tension specifications. (The inconsistent behavior can be easily visualized with the DBplotter.)

Completed weekly cleanroom clean.

=10/15/12=

Sector 1 - Injected a 40 KHz -40 mV peak amplitude pulse into HVTB, connected HVTB to ADB with cables that passed pin-to-pin wire continuity checks with no cross-continuity with other channels (R1 SC4, R1 SC6) and tested ECL output of the ADB from the injected signal.
-Found cable-strain at the connection point on the HVTB was the cause of excessive noise we observed from the amplified ADB signal that was probed from the front panel ports. Slight adjustments of the signal cable stabilize the signal, but if the signal cables ever get bumped the signal goes bad easily and the cables have to be re-adjusted. This problem may be an indication the cable needs to be replaced, or that we need to make sure there's minimal cable strain at the HVTB port.
- With the first probe we used (a 2-pin connector, with one pin grounded) ECL output had significant noise, but the logic signal was present. Switching to a passive 1x grounded scope probe eliminated the noise. We observed ECL pulses at an interval of ~1 μs, width 200ns, peak ~150 mV that aren't triggered by the injected signal. Logic pulses that were in parallel (seem to be triggered by injected pulse) had a wider ~1 μs pulse and 150 mV peak. Switching pins on a given channel does reverse the polarity of the peak (positive vs. negative) as one would expect. We have only tested channels 1 and 2 of the ADB and HVTB so far.

Sector 5 - began stringing Sense wires in SL2. Strung 40 Sense wires (now on SL2 - row 17).

Sector 6 - Marcie is working on compiling a QC document to record any and all issues, actions, etc. that occurred to the chamber during stringing. Pre-potting tension testing is complete. Chamber data is being reviewed and potting will commence once all concerned parties have signed off on the tension data.

=10/16/12=

Just after noon today, the HVAC system went down. All stringing activities were immediately halted and wire, crimp pins, etc. were covered. Upon investigation, it was determined that the blower motor belt had broken. A work order was placed and ISU Facilities replaced the belt at approximately 3:45pm. Temperature and humidity in the cleanroom increased to 75° F and 40%, respectively. Temperatures and particles will be monitored until levels are within specifications before any stringing activities resume.

There was a power bump at 1:25pm that resulted in spikes on the temperature and humidity monitoring graphs. Temperature and humidity levels appear to be recording normally now, although the graphs look distorted. The graphs should appear normal after the spike readings have moved beyond the monitoring periods of each chart. (Temperature: http://hal.iac.isu.edu/cacti-graphs/graph_6.html ) (Humidity: http://hal.iac.isu.edu/cacti-graphs/graph_7.html ).

At approximately 4:15pm cleanroom temperatures dropped below the upper limit of 72° F. The humidity level at that time was 36%.

Sector 1 - began spot testing ECL output on ADB. Changed op-amp on channel 90. Attempted trouble shooting to eliminate noise throughout the system.

Sector 5 - strung 33 Sense wires (now on SL2 - row 28).

Sector 6 - another Field glue contaminated feed through was found (SL2: 28-4 top).

At 5:52pm the last recorded temperature readings by probe number are as follows: (1)71.20°, (2)69.90°, (3)70.20° and (4)69.90°. The humidity level was at 41.20%.

=10/17/12=

Temperatures seem to have stabilized. At 16:45, the daily 5 minute average for each probe was as follows: (1)70.60°, (2)70.17°, (3)70.18°, (4)70.17°. The humidity daily 5 minute average for the same time was 28.66%.

Sector 1 - still trouble shooting to identify noise sources within the system. Started taking screen shots of signals from ECL and ADB front ports.

Sector 5 - strung 54 Sense wires (now on SL2 - row 46).

=10/18/12=

Temperatures are still within specifications. At 17:45, the daily 5 minute average for each probe was as follows: (1)70.49°, (2)70.14°, (3)70.12°, (4)70.11°. The humidity daily 5 minute average for the same time was 21.05%.

Sector 1 - Identified cross-talk occurring on wires/channels near the channel that is having a signal injected. Obtained a new signal cable for HVTB and ADB to try on Monday. Signal cables sent to us use connectors that do not provide strain relief for the knife contacts with the wires in the cable. Had one pull apart, also identified this as a source of poor contact points within the wire that was causing significant amounts of ringing in the ADB-front panel's analog output signals. New cable should take care of this problem. Analyzed output of Ch. 1-14, characterized behavior with existing bad cabling. Also put the "bad" op-amp we identified from Ch. 90 on the HVTB into Ch. 96 and observed ADB and ECL signals with a "good" and "bad" op-amp. Currently the good op-amps in all channels result in two "ragged" pulses per injected pulse in the ADB-front panel's analog signals and variable triggering behavior with the ECL that would result in junk data if hooked up to a TDC. The "ragged" pulses are most likely an artifact of the cabling being used, and should be resolved with the new cabling.

Sector 5 - strung 45 Sense wires (now on SL2 - row 61). Completed weekly Tension Trend test.

Sector 6 - completed weekly Tension Trend test.

Conducted a weekly clean of the cleanroom.

=10/22/12=

Sector 5 - strung 24 Sense wires (now on SL2 - row 61).

=10/23/12=

Sector 1 - Changes in experimental setup:

-Trying a new 34-pin ribbon cable for getting signal from HVTB to ADB

-Using a second probe for the front-panel ADB Analog output ports (Ch. 1 Yellow)

(Orientation of the ribbon and/or the particular channel being probed on the ADB seem to
have a distinct effect on the quality of the signal observed. Two configurations were tried
today.)

Sector 5 - strung 41 Sense wires (now on SL2 - row 83).

Sector 6 - pulled and replaced two more feed throughs (SL1: 130-4F top and SL2: 28-4F top).

=10/24/12=

Sector 5 - strung 51 Sense wires (now on SL2 - row 100).

Sector 6 - restrung wires in replaced feed throughs in both superlayers. Tested those wires and all adjacent wires. Completed continuity testing. Updated pre-potting tension spreadsheets.

=10/25/12=

Sector 5 - strung 42 Sense wires (now on SL2 - row 114). Completed weekly Tension Trend Test.

Sector 6 - completed weekly Tension Trend Test.

Completed weekly cleanroom clean.

=10/29/12=

Conducted potting training with all stringers.

Sector 5 - strung 21 Sense wires (now on SL2 - row 121). Had issues with the left roller on the stringing machine. Replaced balloon but the roller is still not pulling wire through correctly. Tried using one of the rollers from the Sector 6 stringing machine. Still having issues with the wire feed. Will trouble-shoot tomorrow.

Sector 6 - removed stringing rail, etc. in preparation for potting. Began potting top plate in SL2. Completed from row 1 to row 62.

=10/30/12=

Sector 5 - strung 51 Sense wires (now on SL2 - row 138). Stringing machine issues were fixed by replacing rollers with those from the Sector 6 stringing machine. If the Sector 5 rollers can not be repaired, we may need to explore options for replacement. The soft, wool like material that surrounds the rollers is not uniform and causes an uneven surface once the roller is covered with the balloon.

Sector 6 - potted top plate in SL2 from row 63 - 141.

=10/31/12=

Sector 5 - strung 63 Sense wires (now on SL2 - row 159).

Sector 6 - completed potting top plate in SL2. Started potting top plate in SL1 from row 228 - 135.
