Action Items
Preliminary Agenda
- Previous CPP meeting: Apr 12, 2023
- Announcements
- Action Items
- Calibrations
- TOF: Full calibration complete. Tested one run, looks very good, resolution below 100ps (for mean-time). CCDB will be updated soon.
- FCAL: ongoing, needs another "month?", currently good to 5% for pi0 width. issues with the innermost ring, no pi0 seen
- BCAL: was waiting for CDC to be calibrated, did not know it was done. Will proceed on this now.
- CDC: calibration is done. Naomi is working on refinements that do not impact the BCAL efforts. Note that the usual procedure to calibrate the CDC does not work because the Start Counter was not installed. Sean made a procedure to use the BCAL timing instead, however, this may introduce a catch 22?
- FDC: Keigo, done.
- CTOF, FMWPC:
- Digihit integral vs peak 2-d plots for groups of 24 MWPC channels show noise dependence on hit multiplicity in the group.
- Digihit integral vs peak 2-d plots for groups of 24 MWPC channels show noise dependence on hit multiplicity in the group.
- Tagger-Mic, PS, TPOL: ?
- ver10: mic. and hod. timining mostly ok., needs some tweaking of individual channels. PS timing itself looks ok however the relative timing between PS and tagger is off by 4ns(always), this inhibits to do and accidental scaling factor calibration. One block of 5 microscope columns are off regarding energy calibration, it seems the ordering is switched (this seems to be also true for the 80k run period and the 110k run period).
- Accidental Scaling Factor calibration requires Tagger and PS calibration.
- Tagger-Mic, PS, TPOL: ?
