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:
- PEPPo magnet/Solenoid installed on 80/20 (Completed)
- Alignment of big pieces (solenoid, viewer crosses, FC4) completed to ~100 micron tolerances per crew. Still awaiting report. (Completed)
- Area up to transition after solenoid under vacuum; valve/bellow/bpm/spool installed. Pumping down and checking RGA now, but tentatively looks good.
- Install 4 5/8" BPMs after insertion measurements completed; 1 found bad - stealing another. Installing good one to d.s. cross today (4/19).
- Downstream viewer / FC cross assemblies nearly ready to leak check.
- Gun work progressing well:
- Sb evaporation source installed in deposition chamber
- R28 insulator on cathode found punctured on removal Lubricant from HV cable got into gun through insulator, path forward under assessment likely related to gun HV trip on 3/25
- Gun rebuild schedule
- Minor SF6 leak in HV chamber identified; repair later...
Next Week:
- Roof tiles off for HDIce (5/24), Dilution refrigerator craned out (5/25), and then roof tiles replaced again (5/26). SRF (Fisher) will be relocating material on roof to accommodate.
- Have spool pieces made and nipples welded
- Mount bottle rack in Labyrinth; remove gas bottles to rack.
2 weeks:
- Wastewater experiment line fully under vacuum (with flange in place of the thin window).
- Install target mechanism
- Build 80/20 support structure; add mounting plates/brackets/etc. (Pb table components awaiting delivery)
- Pull Heliax from Spectrum analyzer/Control room >> Buncher
- Unistrut mounting for cables - Neal will do when available
- 4th terminal system in Control room under assembly/rebuild
- Break vacuum in FC3 region
- Ready to install Al base plates for FC3 region rework as well as solenoid stand. FC3 plate awaiting machining.
- Items from To-do list...
Engineering
- Insertion measurements completed on 4 5/8" BPMs
- Leo dropped VCG off for installation today.
