Difference between revisions of "Run Planning Meeting Notes, Apr 19-Apr 25, 2018"

Revision as of 07:41, 24 April 2018

Notes from the weekend:
- Production running (~80 % ABU)
Reports:
- Raster scan commissioning Todd: "we are ready for a test with AC DAQ running"
- First collimator scan had issues, Follow up more successful, active target, Total PS rate
- Coherent edge excursions
- The beam energy monitor is slightly anti-correlated with beam current
Issues:
- RCDB issues [1],
- Multiple DAQ crashes
- Goniometer vertical stage tripped again
- Harp scans done in CW [2] [3], we must ask for 1 uA Tune Mode. New paragraph added to shift worker instructions
Run Plan
- Monday
  - Beam studies today, parasitic beam possible.
  - High rate L1 tests
  - High rates test of new CODA version
  - Production running
  - Raster scan
- Tuesday
  - RF recovery
  - Muon chamber removal
  - Walk through
  - Change basses
  - Add lead to profiler
- Wednesday
  - Tour of Hall D. Restricted access. 10:10 am 40 people.
- Thursday
  - TAC run
- Longer term run plan
  - weekly plan
  - Super high current (~500 nA) Raw mode and
AOB

Notes from the previous 24 hours:
- Moved AC to 5 mm hole, installed 100 um W shield
- Production running
Reports:
- high current hit multiplicity in TAGM
- Collimator Scan and results
Issues
- Issues with BCAL timing? (Elton)
- Pair Spectrometer Scalers stopped working, was restarted
- FCAL LEDs cycling was interrupted
- RCDB issues
Run Plan
- High rate tests this afternoon
- Production running
- Fast raster scan deferred until Monday (probably, will hear from PD)
- Longer term run plan
  - weekly plan
AOB

Notes from the previous 24 hours:
- Convergence was adjusted
- Current scan completed
- Production running
Issues:
Reports:
- Results from material scan (Sergey and Lubomir)
- Results from thin diamond, 3.4 mm hole. FDC currents drop, not CDC PS flux comparison PS enhancement increases
- First results from current scan [4] [5] [6]
- CDC current correlation with Y beam position observed again (Beni)
Run Plan
- Access today to
  - Move active collimator to 5 mm hole
  - Attach Pb radiator to profiler
  - Muon chamber inspection
- Production running
  - Harp scan when beam comes back
- Fast raster scan deferred until the required people can be found
- Future studies
  - weekly plan
AOB
