Agenda
Schedule
Rough timetable:
- CMTF tests with C75-1 (late-March - early-June).
- UITF beam line modification
- 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
Long Term Schedule (McCaughan) Gantt
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.
- Gun work progressing well:
- Sb evaporation source installed in depo 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.
- Install 4 5/8" BPMs after insertion measurements completed
2 weeks:
- Build 80/20 support structure; add mounting plates/brackets/etc. (Pb table components awaiting delivery)
- Pull Heliax from Sprectrum analyzer/Control room >> Buncher
- Unistrut mounting for cables / gas bottle rack - 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 in progress on 4 5/8" BPMs
