Tuesday March 7

Past 24 hours

Shift Reports

Early Riser Day Swing Owl

Reports

Issues

• AC Vbias tripped yesterday afternoon
• Tagger NMR did not lock initially until reboot
• Magnet was not properly restarted, MCC This is believed by RC and Owl SL to be correlated with the HALO and TAGH voltages tripping and TAGH readouts showing 0 and requiring hard IOC reboot. Possibly poorly positioned beam.
• Crates not communicating back (Hovanes)
• HALO Alarm

Alarms During Maintenance

• Tagger Magnet Alarm, cleared
• TPOL
• DIRC
• CDC p_diff

Plans

• High Current Testing- IP

  • 2 runs PARA (45/135)
  • 2 runs PERP (45/135)
  • 1 run AMO (use it to rejuvenate AMO reference in CBREM EPICS GUI)
• almost time for a harp scan?

• Production runs (Late MCC Swing and Owl)
• After separate ACC issue beam came back 22:05 or so. Thought we were not reaching Richard so I gave him a call at 22:30 just to make sure. Call is successful and Richard goes ahead and does studies on the TagM gains

Early Riser Day Swing Owl

Reports

• second atmospheric pressure sensor added (Hovanes)
• 5x5 Sciglass Detector Prototype (Sasha)

Issues

• Coherent peak
• Tagger magnet tripped off (MCC - Daniel)
• RF TDC

Plans

• Production (300 nA, 2h runs) with cycle:
  • 2 runs PARA (0/90)
  • 2 runs PERP (0/90)
  • 2 runs PARA (45/135)
  • 2 runs PERP (45/135)

• Sasha left segments of detector prototype for RadCon survey on Survey Table. He looks to ask the likes of Scot for guidance as RadCon will have to come when beam is down for a sustained period time.
• Will we need a harp scan? MCC took away beam quite a while yesterday (nearly 14 hours before we got beam back)
