Difference between revisions of "Run Planning Meeting Notes, Mar 12-Mar 18, 2020"

Revision as of 07:26, 18 March 2020

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

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
- threshold scan of TAGH completed -- Sasha
- difficulties with DIRC hv, resolved -- Justin
- drop in collimator transmission by 20% -- Alexander
Reports/Issues
- strange pattern in fdc occupancy -- Alexander
- fadc250 data corruption issue? -- Beni
  - problem narrowed down to one fadc250 module
- 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?
Run Plan
- TAC run to be taken opportunistically, when Hall A is down -- Sasha
- Plan to instrument active collimator with a reference electrode bias -- Richard
- Tagger microscope intensity scan with diamond radiator requested (1 shift) -- Richard
- Production
Jlab at MEDCON 5 -- starting tomorrow!

Jlab at MEDCON 5 -- starting today!
- Continuous bluejeans meeting open in counting house
- Hall D going to single-person shifts starting today at 16:00
Last 24 hours
- fcal PDU reboot recovers missing channels -- Colin
- raw mode run 72291 (30 minutes of beam) was taken, then production continued
- fadc250 in FCAL7 slot 3 replaced
Reports/Issues
- Notches in TAGM timing histos fixed, (online software rebuild) -- Alexandre
- Removed several timing macros from rootspy
- Collimator transmission trends update -- Alexandre
Run Plan
- New BCal pedestal run requested -- Mark
- TAC run planned for Wednesday morning, starting 7:00am when Hall A plans a Moller run -- Sasha
- Plan to instrument active collimator with a reference electrode bias -- Richard
- Tagger microscope intensity scan with diamond radiator requested (1 shift) -- Richard
- Other systematics studies?
  - Low-intensity scans to study reconstruction efficiency dependence on photon intensity: suggested run plan and list of runs from 2018 scans
- Building access at MEDCON 5

Single-person shift schedule in operation, since yesterday 16:00
- the schedule, linked from main Hall-D web page -- Eugene
- the shift rules, linked from main Hall-D web page -- Eugene
- the shift rules, linked from hdops wiki -- Eugene
- 4-hall video feeds are now available, displayed on screen above copier
  - on-site access only, please
- Continuous bluejeans meeting open in counting house -- in preparation
Last 24 hours
- BCal pedestal adjustment -- completed
  - one hot channel now showing up
- increased occupancy seen in one fdc plane -- deemed ok
- PS scalers missing, left arm
- fire alarm box beeping -- guidance?
- tagger microscope intensity scan -- completed, 7 hours
  - Tagger microscope intensity scan with diamond radiator
- Empty target run -- completed, 2 hours
- Low-intensity scans to study reconstruction efficiency dependence on photon intensity -- completed
  - low-intensity run sequence
Reports/Issues
- What to do about BTA reporting, with 8-hour / 6-hour shift boundary mismatch?
- Plan implemented for offsite workers to do regular monitoring, make reports
  - 6:00pm report March 17
Run Plan
- TAC run -- starting this morning 7:00am
