<- Back to Run Coordination Meetings:Fall2017 Spring2018 Run
Contents
Thursday, April 12 at 08:45
- Notes from the previous 24 hours:
- TAC run (evening strip chart) was finished around 10pm. Took data with both the 750um and 75um converter.
- Production started around 11 pm and has continued through the night.
- Issues:
- When adjusting a procedure, please contact the expert before doing so to make sure the changes you make are okay.
- ~1hr 20 mins of DAQ issues while the target was filling and we could not run in raw mode.
- PS scalers (Alexandre)
- Reports:
- Correlation between beam Y position and CDC HV current (Beni)
- Attenuation lengths (Lubomir)
- PS acceptance from TAC run with 1/3 of data (Sasha)
- Low Level Monitoring Report (Thomas)
- Run Plan
- Pass change this morning
- Short access to install copper and tungsten shields
- Move muon chamber back into beam line
- Production running
- Harp scan when beam comes back
- Fast raster scan postponed to Monday
- Any more systematic studies we want to do?
- Pass change this morning
- AOB
Friday, April 13 at 08:45
- Notes from the previous 24 hours:
- No beam until 4pm
- Finished materials scan at 5:35pm
- Finished raw mode run
- Bill broke the 7hr mark for ABU during his shift- first time a hall has done that this spring
- Muon chamber installed with the steel bar
- New radiator on GEM TRD
- Shields installed on profiler
- Issues:
- Bill noticed some minor inconsistencies with monitoring plots (beta vs. p, beam energy, and trigger bit)
- Reports:
- Harp scan (Hovanes)
- Materials scan (Lubomir)
- Low level monitoring (Thomas)
- Run Plan
- Todd wants to try a low current lock on the active collimator at ~1pm
- Trigger studies (~2hr)
- Hovanes and Sasha need to test V wire and lock on active collimater (~10 minutes)
- Production and switching to the thin diamond next week
- AOB
- Have Lubomir for opportunistic access to remove Cu and half of W shield- any others? Beam studies on Monday and RF recovery Tuesday
- Run meeting this weekend?
