Integrated Trigger Count

Friday March 3

Past 24 hours

• RadCon surveyed the detector prototype and it has been removed
• ACC downtimes: 2L25 solenoid, BLM trips, 1L09 HV
• Harp scan in Swing. The fits are "OK" though there have probably been better
• Richard Jones does Normalization run using AMO with only Row 4 of TAGM to further the study.
• OWL: resume production

Shift Reports

Early Riser Day Swing Owl

Reports

• 100V 500V ISEG locations(Mark)
• RF TDC cable reconnected (Lubomir)
• CCAL crate added to DAQ config (Sasha)
• Special running part 2 (Richard)

Issues

• Administrative: Error Connecting to VNC Suite - port 33 somewhat got killed. use 5901 or 5902 - part of it is my fault, due to remembering the wrong password...
• DIRC alarms becoming more frequent [1] [2] [3] [4]

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)
