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.

The clean room needs space for instrumenting.  The DC will be layed horizontal so PC cards can be mounted and tested.

11' = hook height in stringing clean room
 
−
 
−
There are 2 stringing strong back and 6 shipping strong backs.  They bolt on separate sides of the chambers.
 
−
<pre>
 
−
Idea:  Instrument the chamber on the ledge above the squash court. 
 
−
Put a lift on the pole which we can use to turn the DC from its standing (stringing) position to
 
−
its horizontal (instrumentation) position then "swing" it over onto the squash court ledge.
 
−
</pre>
 
−
 
−
No Halogen lighting.
 
−
 
−
Think about air conditioning.  People are space heaters.
 
−
 
−
Have shoes specific for clean room instead of booties.

==== Pros and Cons of Locations====
 
−
 
−
;Physics Basement
 
−
 
−
;Pros:
 
−

−
    20x39x15'  -vs- 20x40x20;
 
−
 
−
2.) more quality control: 4 Physics professors more likely to look in on construction in between classes
 
−
 
−
3.)established record of temperature control
 
−
 
−
4.) closer to other facilities; machine shops, electronics, ...
 
−
 
−
;Cons
 
−
1.) must move detector standing up to get through 6' hallway

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.

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

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
