After testing tensions and removing the R2 pretensioner, we noticed two loose wires hanging in the chamber. Both had tension errors within the acceptable range when tested earlier. We pulled the wires out the top and examined them. They appeared to have a crimp mark on the bottom. We retested the gap of both crimpers being used and found that the ones on the bottom were not holding the gauged gap. (Both sets of crimpers had been tested immediately after lunch and before beginning stringing in the afternoon.) We visually inspected the wires we had strung and saw no other loose or hanging wires. Debbie made adjustments to the crimpers and replaced the spring. They appear to be holding their gap now. Marcie cleaned and mopped the clean room floor while stringing was temporarily halted. We are ready to begin stringing again in the morning.

After testing tensions and removing the R2 pretensioner, we noticed two loose wires hanging in the chamber. Both had tension errors within the acceptable range when tested earlier. We pulled the wires out the top and examined them. They appeared to have a crimp mark on the bottom. We retested the gap of both crimpers being used and found that the ones on the bottom were not holding the gauged gap. (Both sets of crimpers had been tested immediately after lunch and before beginning stringing in the afternoon.) We visually inspected the wires we had strung and saw no other loose or hanging wires. Debbie made adjustments to the crimpers and replaced the spring. They appear to be holding their gap now. Marcie cleaned and mopped the clean room floor while stringing was temporarily halted. We are ready to begin stringing again in the morning.

After testing tensions and removing the R2 pretensioner, we noticed two loose wires hanging in the chamber. Both had tension errors within the acceptable range when tested earlier. We pulled the wires out the top and examined them. They appeared to have a crimp mark on the bottom. We retested the gap of both crimpers being used and found that the ones on the bottom were not holding the gauged gap. (Both sets of crimpers had been tested immediately after lunch and before beginning stringing in the afternoon.) We visually inspected the wires we had strung and saw no other loose or hanging wires. Debbie made adjustments to the crimpers and replaced the spring. They appear to be holding their gap now. Marcie cleaned and mopped the clean room floor while stringing was temporarily halted. We are ready to begin stringing again in the morning.

According to http://www.set3.com/standards.html

Originally Federal Standard 209E defined a class 10,000 clean room based on the particle counts given below. A class 10,000 clean room is currently defined as an ISO 7 clean room using the ISO standard 146441.

After testing tensions and removing the R2 pretensioner, we noticed two loose wires hanging in the chamber. Both had tension errors within the acceptable range when tested earlier. We pulled the wires out the top and examined them. They appeared to have a crimp mark on the bottom. We retested the gap of both crimpers being used and found that the ones on the bottom were not holding the gauged gap. (Both sets of crimpers had been tested immediately after lunch and before beginning stringing in the afternoon.) We visually inspected the wires we had strung and saw no other loose or hanging wires. Debbie made adjustments to the crimpers and replaced the spring. They appear to be holding their gap now. Marcie cleaned and mopped the clean room floor while stringing was temporarily halted. We are ready to begin stringing again in the morning.

After testing tensions and removing the R2 pretensioner, we noticed two loose wires hanging in the chamber. Both had tension errors within the acceptable range when tested earlier. We pulled the wires out the top and examined them. They appeared to have a crimp mark on the bottom. We retested the gap of both crimpers being used and found that the ones on the bottom were not holding the gauged gap. (Both sets of crimpers had been tested immediately after lunch and before beginning stringing in the afternoon.) We visually inspected the wires we had strung and saw no other loose or hanging wires. Debbie made adjustments to the crimpers and replaced the spring. They appear to be holding their gap now. Marcie cleaned and mopped the clean room floor while stringing was temporarily halted. We are ready to begin stringing again in the morning.

After testing tensions and removing the R2 pretensioner, we noticed two loose wires hanging in the chamber. Both had tension errors within the acceptable range when tested earlier. We pulled the wires out the top and examined them. They appeared to have a crimp mark on the bottom. We retested the gap of both crimpers being used and found that the ones on the bottom were not holding the gauged gap. (Both sets of crimpers had been tested immediately after lunch and before beginning stringing in the afternoon.) We visually inspected the wires we had strung and saw no other loose or hanging wires. Debbie made adjustments to the crimpers and replaced the spring. They appear to be holding their gap now. Marcie cleaned and mopped the clean room floor while stringing was temporarily halted. We are ready to begin stringing again in the morning.

After testing tensions and removing the R2 pretensioner, we noticed two loose wires hanging in the chamber. Both had tension errors within the acceptable range when tested earlier. We pulled the wires out the top and examined them. They appeared to have a crimp mark on the bottom. We retested the gap of both crimpers being used and found that the ones on the bottom were not holding the gauged gap. (Both sets of crimpers had been tested immediately after lunch and before beginning stringing in the afternoon.) We visually inspected the wires we had strung and saw no other loose or hanging wires. Debbie made adjustments to the crimpers and replaced the spring. They appear to be holding their gap now. Marcie cleaned and mopped the clean room floor while stringing was temporarily halted. We are ready to begin stringing again in the morning.

After testing tensions and removing the R2 pretensioner, we noticed two loose wires hanging in the chamber. Both had tension errors within the acceptable range when tested earlier. We pulled the wires out the top and examined them. They appeared to have a crimp mark on the bottom. We retested the gap of both crimpers being used and found that the ones on the bottom were not holding the gauged gap. (Both sets of crimpers had been tested immediately after lunch and before beginning stringing in the afternoon.) We visually inspected the wires we had strung and saw no other loose or hanging wires. Debbie made adjustments to the crimpers and replaced the spring. They appear to be holding their gap now. Marcie cleaned and mopped the clean room floor while stringing was temporarily halted. We are ready to begin stringing again in the morning.

It was brought to our attention this afternoon, by Dr. McNulty, that we need to keep a separate work log to record who is stringing, clean-room temperatures, etc. We were tasked with creation of a new Excel file for this purpose and will transfer our existing records to this file tomorrow.

=4/18/12=

Strung 98 Field wires.

Reattached part of the clean room wall that had fallen.

=4/19/12=

Strung 49 Field wires.

After testing tensions and removing the R2 pretensioner, we noticed two loose wires hanging in the chamber. Both had tension errors within the acceptable range when tested earlier. We pulled the wires out the top and examined them. They appeared to have a crimp mark on the bottom. We retested the gap of both crimpers being used and found that the ones on the bottom were not holding the gauged gap. (Both sets of crimpers had been tested immediately after lunch and before beginning stringing in the afternoon.) We visually inspected the wires we had strung and saw no other loose or hanging wires. Debbie made adjustments to the crimpers and replaced the spring. They appear to be holding their gap now. Marcie cleaned and mopped the clean room floor while stringing was temporarily halted. We are ready to begin stringing again in the morning.

It was brought to our attention this afternoon, by Dr. McNulty, that we need to keep a separate work log to record who is stringing, clean-room temperatures, etc. We were tasked with creation of a new Excel file for this purpose and will transfer our existing records to this file tomorrow.

Strung 98 Field wires.

Reattached part of the clean room wall that had fallen.

=4/19/12=

Strung 49 Field wires.

After testing tensions and removing the R2 pretensioner, we noticed two loose wires hanging in the chamber. Both had tension errors within the acceptable range when tested earlier. We pulled the wires out the top and examined them. They appeared to have a crimp mark on the bottom. We retested the gap of both crimpers being used and found that the ones on the bottom were not holding the gauged gap. (Both sets of crimpers had been tested immediately after lunch and before beginning stringing in the afternoon.) We visually inspected the wires we had strung and saw no other loose or hanging wires. Debbie made adjustments to the crimpers and replaced the spring. They appear to be holding their gap now. Marcie cleaned and mopped the clean room floor while stringing was temporarily halted. We are ready to begin stringing again in the morning.

It was brought to our attention this afternoon, by Dr. McNulty, that we need to keep a separate work log to record who is stringing, clean-room temperatures, etc. We were tasked with creation of a new Excel file for this purpose and will transfer our existing records to this file tomorrow.

Strung 98 Field wires.

Reattached part of the clean room wall that had fallen.

=4/19/12=

Strung 49 Field wires.

After testing tensions and removing the R2 pretensioner, we noticed two loose wires hanging in the chamber. Both had tension errors within the acceptable range when tested earlier. We pulled the wires out the top and examined them. They appeared to have a crimp mark on the bottom. We retested the gap of both crimpers being used and found that the ones on the bottom were not holding the gauged gap. (Both sets of crimpers had been tested immediately after lunch and before beginning stringing in the afternoon.) We visually inspected the wires we had strung and saw no other loose or hanging wires. Debbie made adjustments to the crimpers and replaced the spring. They appear to be holding their gap now. Marcie cleaned and mopped the clean room floor while stringing was temporarily halted. We are ready to begin stringing again in the morning.

After testing tensions and removing the R2 pretensioner, we noticed two loose wires hanging in the chamber. Both had tension errors within the acceptable range when tested earlier. We pulled the wires out the top and examined them. They appeared to have a crimp mark on the bottom. We retested the gap of both crimpers being used and found that the ones on the bottom were not holding the gauged gap. (Both sets of crimpers had been tested immediately after lunch and before beginning stringing in the afternoon.) We visually inspected the wires we had strung and saw no other loose or hanging wires. Debbie made adjustments to the crimpers and replaced the spring. They appear to be holding their gap now. Marcie cleaned and mopped the clean room floor while stringing was temporarily halted. We are ready to begin stringing again in the morning.

It was brought to our attention this afternoon, by Dr. McNulty, that we need to keep a separate work log to record who is stringing, clean-room temperatures, etc. We were tasked with creation of a new Excel file for this purpose and will transfer our existing records to this file tomorrow.

=4/18/12=

Strung 98 Field wires.

Reattached part of the clean room wall that had fallen.

=4/19/12=

Strung 49 Field wires.

After testing tensions and removing the R2 pretensioner, we noticed two loose wires hanging in the chamber. Both had tension errors within the acceptable range when tested earlier. We pulled the wires out the top and examined them. They appeared to have a crimp mark on the bottom. We retested the gap of both crimpers being used and found that the ones on the bottom were not holding the gauged gap. (Both sets of crimpers had been tested immediately after lunch and before beginning stringing in the afternoon.) We visually inspected the wires we had strung and saw no other loose or hanging wires. Debbie made adjustments to the crimpers and replaced the spring. They appear to be holding their gap now. Marcie cleaned and mopped the clean room floor while stringing was temporarily halted. We are ready to begin stringing again in the morning.

It was brought to our attention this afternoon, by Dr. McNulty, that we need to keep a separate work log to record who is stringing, clean-room temperatures, etc. We were tasked with creation of a new Excel file for this purpose and will transfer our existing records to this file tomorrow.

=4/18/12=

Strung 98 Field wires.

Reattached part of the clean room wall that had fallen.

=4/19/12=

Strung 49 Field wires.

After testing tensions and removing the R2 pretensioner, we noticed two loose wires hanging in the chamber. Both had tension errors within the acceptable range when tested earlier. We pulled the wires out the top and examined them. They appeared to have a crimp mark on the bottom. We retested the gap of both crimpers being used and found that the ones on the bottom were not holding the gauged gap. (Both sets of crimpers had been tested immediately after lunch and before beginning stringing in the afternoon.) We visually inspected the wires we had strung and saw no other loose or hanging wires. Debbie made adjustments to the crimpers and replaced the spring. They appear to be holding their gap now. Marcie cleaned and mopped the clean room floor while stringing was temporarily halted. We are ready to begin stringing again in the morning.

=4/20/12=

Strung 77 Field wires and completed trend testing for this week.

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.

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?

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.

[[File:Clean_Air_Quote_No_Filters.pdf]]

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.

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?
