Monday, April 4
- Accelerator Status
- No beam or poorly positioned beam until ~3:30am Sunday April 3
- Bleedthrough from Hall-A
- Accelerator experts convening this morning to form plan for fixing issues with beam. May be disruptive today or tomorrow morning as they implement plan
- Hall A gets priority Today
- Hall-D/GlueX items
- Completed empty target run with amorphous radiator
- Difficulty getting consistent PARA and PERP at same location on JD70-118. Switch to JD70-119.
- CDC HV trips frequently. Current trip levels had inadvertently been reduced to 2uA (fixed)
- beam intensity fluctuations
- Hovanes suggests regular harp scans, including two ACC harps in D beamline, MCC must do those
- Request accelerator formalize scan procedure for 5C11 and 5C11B. Todd will write something up
- other systems?
- Run Plan
-
empty target run -
Satellite peak study (move beam) - PS magnet current studies
- TRD run
- DAQ Studies
- Microscope alignment (Alex B.)
- Production running
-
- Offline analysis?
- AOB?
Sunday, April 3
- Accelerator Status
- Beam was gone until ~2am Saturday April 2
- Frequent RF trips, poor profile scans, poor enhancement
- Spotty or unacceptably poor beam from 13:00 Saturday to 3:30 Sunday (Issues with bleedthrough from other halls (?))
- Improved beam profile
- Hall A gets priority Monday
- Hall-D/GlueX items
- Completed empty target run with both PARA and PERP orientations
- Difficulty getting consistent PARA and PERP at same location on JD70-118. Switch to JD70-119.
- CDC HV trips frequently
- beam intensity fluctuations
- tagger harp scan shows sigma_x = 0.9 mm, sigma_y = 1.1 mm, possibly better focusing on collimator
- Hovanes suggests regular harp scans, including two ACC harps in D beamline, MCC must do those
- Shift-takers run comments: Discussion deferred
- other systems?
- Run Plan
-
empty target run - PS magnet current studies
- TRD run
- Satellite peak study (move beam)
- Microscope alignment (Alex B.)
- production running
-
- Offline analysis?
- AOB?
