March 7 2014
- Delays prevented Windows from being installed. They should be installed this weekend.
- Final plugs and standoffs will be glued in today
- remove chamber from clean room Sunday
- Get shipping pallets for lifts, A-frames, the last chamber, and small equipment
- Schedule pickup for Friday March 28 so the chamber arrives at JLab during the following week
Plan is to wire wrap, install boards, HV test to 100 Volts in air, and install board covers.
Get Carriage bolts for drift chamber lifting frame
Check that brass screws for windows are in.
Shrink wrap for the last two chambers.
Information to find:
A-frame dimensions:
- Base Width (dimension perpendicular to the rotation cylinder): 57"
- Base Depth (dimension parallel to cylinder): 52"
- Base Depth (including mounting points at top): 68"
- A-frame plumb (vertical) height: 79"
Note: vertical height includes the height added by a metal end-piece that connects to the cylinder's mounts.
- A-frame side-length (structural member connecting base to top of "A"): 84"
- Carriage bolt length for nose-piece of chamber lifting structure: 5.25" long, 1" coarse thread
March 8 2014
Installation of mylar windows complete. All plugs and plastic stand-offs installed.
March 19 2014
- Wire wrap is ~70% done
- 2 suspension boots installed on chamber pallets.
March 20 2014
- Wire wrap is ~85% done
- All suspension boots installed on pallets. A-frame pallet is finished.
Remaining tasks:
HV Testing
- Segment wire-wrap
- Install HV boards, conductive boots & the 'kraken'
- Do 100/50/20V test on wire-types to check for crossed-wires & excess current draw (what's our metric for success w/ current draw? 10 micro-amps?)
Assuming no problems with HV testing...
- Try placing a chamber onto a suspension-boot pallet. (do we want to try both chambers? do they need to be packaged first?)
- Cut and install 3mil dust covers on S2, Re-do dust cover on one side of S1 (it's been sliced open and isn't repairable)
- Move A-frame out of clean-room and onto a pallet. (store outside) (how do we strap down the A-frame & cylinder? Is there a particular method?)
- Move both scissor-lifts out and onto pallets.
- Organize miscellaneous lab materials for shipping back to J-lab on pallets. (need the metal-strap crimping device back)
* Put padding/bubble-wrap back on the extra set of HV boards we didn't install before shipping.
