1. Notes from the weekend:
   • Production running (~80 % ABU)
2. 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
   • [https://logbooks.jlab.org/entry/3564954 Coherent edge excursions
3. 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
4. Run Plan
   • Monday
     • Beam studies today, parasitic beam possible.
     • High rate L1 tests
     • High rates test of new CODA version
     • Production running
   • Tuesday
     • RF recovery
     • Muon chamber removal
   • Longer term run plan
     • weekly plan

2. Reports:
   • high current hit multiplicity in TAGM
   • Collimator Scan and results
3. Issues
   • Issues with BCAL timing? (Elton)
   • Pair Spectrometer Scalers stopped working, was restarted
   • FCAL LEDs cycling was interrupted
   • RCDB issues
4. Run Plan

1. Notes from the previous 24 hours:
   • Convergence was adjusted
   • Current scan completed
   • Production running
2. Issues:
3. 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)
4. 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
