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.

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.

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.

;6/28/11

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.

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.

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

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

The visual inspection of the drift chamber wires after stringing led to the discovery of a variation of the wire appearance.  There isn't a clear indication if this variation has an impact on the wire quality

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?

Items From JLab
$2,500 Crane to mount DC (use grant to buy)
(Done) comes with stringing fixtures!. platform to take chamber from upper level to lower
JLab will order 2 Man Lifts to reach 15'
Primary magnets for wire tension measurements will be sent by JLab (We have budgeted for power supply get one that is 15 V, 100 amp Analog better than switching)


Task list

  1. Secure strip door
  2. Drill holes and Mount braces for seismic....geo....something requirements
  3. Make door for storage area under stairs
  4. Get 480 V outlets installed - Currently in progress. Estimated completion date: September 23, 2011.
  5. Order changing room items (bench, storage rack for clothes)
  6. Fix vinyl wall around fixture (need to install snaps)
  7. Mount power supply under fixture. Attach coil wires to power supplies (terminal ends for 1 gauge wire? maybe from an automotive store for battery cables)
  8. Find/build tray for manlift (1-2 feet wide , 6 inches deep) - Grainger part number: 2NXN5.
  9. Test stringing machine
  10. Door for entrance to clean room
  11. Cordless phone for cleanroom (call telecommunications 4541, 4900) Beam lab #2631
  12. Build adjustable pulley for bottom stringer
  13. Build chain weights for stringing
  14. Build tension weights
  15. Order torque wrench (in*lbs) – contact Steve Christo for part number. More than likely this is an expensive item, might cost $200-300 from Snap-On...maybe
  16. Order several power strips (min 3) - may need extension cords also
  17. Hard door for changing room

Order

  1. Scale - prefer digital that can measure to 1/10th gram. I put a link on the wiki page but I'm sure we can find this locally
  2. Dremel engraving bit
  3. Order snap fasteners ~100

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

Wire Tension

A Helmholtz coil is used to test the wire tension

CLAS6 R1 wire tension measurement technique NIM article

File:CLAS6 DCWireTensMeasTech 1996.pdf

Below is a write up from BaBar

File:Device2MeasureWireTension Covery BaBarReportTNDC-96-39 1996.pdf

File:ODU WireTensionMeasurements 10-2009.pdf

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

http://clasweb.jlab.org/drawings/CLAS12/DRIFT_CHAMBERS/Helmholz_calculator.xls

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

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.

Region 1 Q &A

The voltage ratio should be S:F:G=2:1:5/7 (1500:-750:535).

Wire quality

The visual inspection of the drift chamber wires after stringing led to the discovery of a variation of the wire appearance. There isn't a clear indication if this variation has an impact on the wire quality
