Friday March 3

Past 24 hours

• RadCon surveyed the detector prototype and it has been removed
• ACC downtimes: 2L25 solenoid, BLM trips

Shift Reports

Early Riser Day Swing [ Owl]

Issues

• Administrative: Error Connecting to VNC Suite - port 33 somewhat got killed. use 5901 or 5902
• DIRC alarms becoming more frequent

Plans

• TAC Run (Sasha/Alexandre)
• 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)
  • 1 run AMO (use it to rejuvenate AMO reference in CBREM EPICS GUI)

Thursday March 2

Past 24 hours

• MCC "Maintenance Day"
• TAGM diagnosis, row checks
• 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

Shift Reports

Early Riser Day Swing Owl

Reports

• second atmospheric pressure sensor added (Hovanes)
• 5x5 Sciglass Detector Prototype (Sasha)
• rho yields addressing TagM Issue (Alex)
• FDC wire discrepancy update (Lubomir)
• CDC AI HV control enabled (David L)
• Beam time structure(Hovanes)
• TAGM efficiency checks (Justin)
• Special TAGM Row 4 Runs (Richard)

Issues

• Coherent peak
• Tagger magnet tripped off (MCC - Daniel)
• RF TDC
• MCC reports some phase shifts for beam @ 5th pass (all halls)

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)
  • 1 run AMO (use it to rejuvenate AMO reference in CBREM EPICS GUI)

• 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)
