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

R1 Construction preparations

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.

Readiness Review

CLAS12R1ReadinessReview2011

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

Standard operating pressure is 0.05" inches of water.

the bubbler exhaust tip should barely touch the oil enough to cause bubbles.
