Agenda
Schedule
Long Term Schedule: Gantt (Outstanding tasks)
- Supplementary Shielding Installation: Mid-June
- Beamline Commissioning / Test Plans / Shielding Verification
- 7/26/21 Start Hot Check-out
- Commission new beam line and execute experiment
- Science!!!
New items for discussion:
Short term schedule update:
This week:
- Elevated beam line terminated in pump and RGA leak checked
- Experimental beam line under vacuum with thin window attached, RGA leak check required.
- Vacuum pumping down well, but light bake may be required once we have completed installation.
- STAC5 controller for chopper configured, installed, and tested.
- FC3 region vented, purged, and mostly reconfigured.
- Go ahead given by division management for FML to procure concrete shielding using funds from LDRD and UITF (10K+30kprocurement+30K AIP/Labor reapportionment)
Still to do:
- Finish FC3 region vacuum work.
- Install target mechanism
- Add Mu metal over bellows on wastewater line.
- EES may start cabling downstream section & making UED updates.
- Gun work progressing well:
- HV chamber evaluation - plan to bake to evaporate lubricant & pump it off, install photocathode, and bake again.
- First bake went well, despite an unexpected power outage.
- Test lab procedures updated to contact UITF and Polarized source group in event of power outages in the future.
- Sb source laser aperture added in depo chamber; aligned to laser path.
- Mask alignment examined
- Pucks prepared for next run
- Gun rebuild schedule
- Minor SF6 leak in HV chamber identified; repair later...
Next Week:
- Build 80/20 support structure; Pb table components awaiting delivery. (status update?)
- Ready to install Al base plates for FC3 region rework as well as solenoid stand. FC3 plate awaiting machining.
- Mount bottle rack in Labyrinth; remove gas bottles to rack.
- Unistrut mounting for cables - Neal will do when available
2 weeks:
- Pull Heliax from Spectrum analyzer/Control room >> Buncher
- 4th terminal system in Control room under assembly/rebuild
- Items from To-do list...
