Thursday, October 21
- Last 24h:
- No beam from 5:20pm Tuesday until 2am Thurs due to LCW/power problem
- Work done during the access:
- magnetic field measurements around CCAL
- 15 FCAL bases replaced and re-terminated one cable
- faulty FDC chiller replaced
- rebalanced the server power load on rack 13
- ? position survey CCAL ?
- ? correct shielding at the left (downstream) PS arm ?
- Remaining issues:
- Tagger hodoscope time shifts
- communication with accel. w.r.t. tagger magnet - Paul Vasilauskis (Ops group leader): "I am putting out to my staff to contact the hall if they do need to touch the magnet and am looking into adding wording to the magnet screens"
- BCAL noise at 10 o'clock
- Bleedthrough
- Plan:
- When the beam is back continue production at 200nA after the usual checks (radiation levels & harp scans)
- Continue running with the solenoid on & target full until Friday or later
- Pass change possible Friday or Saturday
- Expect some downtime Monday daytime for VIP tour
