Contents
Thursday, March 12
- Last 24 hours
- DAQ "data corruption" error from FCAL crate -- seen before?
- 10% drop in PS coincidence rate seen at beginning of new run, 04:42
- Reports/Issues
- new labels on trigger monitoring plot
- Root-spy guidance help pages -- already implemented, thanks David!
- default page is brief explanation + expert to call in case of questions, issues
- experts can add instructions if they want to be called less often
- updates to text are through github -- project??
- Run Plan
- Production
Friday, March 13
- Last 24 hours
- DigiHits_occupancy monitoring plots missing? -- Naomi
- HV raised on many (25) TAGH channels -- Beni
- beam unstable (when available) during afternoon -- Alexander
- beam energy step, 2 MeV, understood -- Reinhard
- Reports/Issues
- updates to rootspy guidance
- bubblers at add line ok? -- Mariana
- apparent changes in BCal attenuation lengths -- Mark Dalton
- LED ref TDC monitoring plot missing? -- Mariana
- rapid drop in transmission close to 15% -- Alexandre
- Run Plan
- Tentative new make-shift schedule
- TAC run today, after Hall C done
- Production
For the period starting evening of Tuesday, March 17
Tentative Revised Shift Schedule -- Viral Edition
Monday, March 16
- Last 72 hours
- TAGH hv adjustments, recovery of failed channel -- Beni
- TAC run impossible, bleed-through from Hall A? -- Sasha
- snake scan of CCAL completed -- Sasha

- unable to reproduce notch structure around coinc peak in TAGM timing monitoring plot -- Richard
- standard guidance on how to reproduce monitoring plots following fixes?
- repeated DAQ start issues resolved by rebooting rocs
- shift crew is losing time retrying failed starts, often blind to what is blocking.
- can we get standard guidance on how to find which roc is holding busy?
