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.

Environmental control needed
Temperature control constraint is
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.
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.
The temperatures measured after changing the temperature set point to 72.
Temperature Oscillations observed before adding a tarp over the large doorway
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.
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.
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.
Below is a plot of the temperatures recorded over the last 7 days (4/21 - 27 / 11) . There appears to be a slow rise?
- 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
- 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.
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?

An excel spreadsheet to calculate fields for such coils is given at

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. CLAS12_R1_Prototype_9-16-07

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.
