Short term schedule update:
This week:
- Area up to transition after solenoid under vacuum. RGA leak check completed.
- Downstream viewer / faraday cup assembly under vacuum. RGA leak check completed.
- One 4 5/8" BPM failed insertion checks, second 4 5/8" BPM stolen from elevated line has stripped hole (re-tap later), 3rd one removed and installed.
- Spool pieces installed on both sides of 1st cross (one last one remaining); all but ~2 feet of beam line now under vacuum and leak checked.
- Roof tiles off for HDIce (5/24), Dilution refrigerator craned out (5/25), and then roof tiles replaced again (5/26).
- Last spool piece under fabrication.
- Gun work progressing well:
- HV chamber evaluation - plan to bake to evaporate lubricant & pump it off, install photocathode, and bake again.
- Gun rebuild schedule
- Minor SF6 leak in HV chamber identified; repair later...
Next Week:
- Mount bottle rack in Labyrinth; remove gas bottles to rack.
- Wastewater experiment line fully under vacuum (with flange in place of the thin window).
- Install target mechanism
- Build 80/20 support structure; Pb table components awaiting delivery.
- Unistrut mounting for cables - Neal will do when available
- Break vacuum in FC3 region
- Ready to install Al base plates for FC3 region rework as well as solenoid stand. FC3 plate awaiting machining.
2 weeks:
- Add Mu metal over bellows on wastewater line.
- Switch Wastewater line Vacuum HV from local supplies to house power. Make UED updates as appropriate for vacuum system.
- Pull Heliax from Spectrum analyzer/Control room >> Buncher
- 4th terminal system in Control room under assembly/rebuild
- Items from To-do list...
