Old List

Need to do

  • Analyze the FCAL LED skim
    • Extract pedestals for each run
    • Bad blocks table for each run
  • Recalibrate inner FCAL blocks
    • Igal says that if we keep the same 2 calibration periods, he is ready to recalibrate and this should take maybe a couple of weeks
      • Gains (2 tables)
        • 93676 2017-11-16 10-03-20 2017-11-16 10-03-20 default 30000L-30788L

      • Pedestals (3 tables)

      • Timing offsets (1 table)
        • 82585 2017-10-27 12-55-09 2017-10-27 12-55-09 default 30000L-inf
    • Decide if we should use the Primex calibration procedure
    • Also decide if we should use log-weighted or weighted mean (current default) position
    • Igal: Simon is working on finalizing the Island reconstruction algorithm - maybe we want to use this instead
  • Update CDC calibrations
  • Decide whether to raise the CDC thresholds in software
  • Check tagger calibrations
  • Update TOF calibrations
  • Fix alignment of start counter
  • Benchmark reconstruction software against 2019-11 software version
  • Revisit how we handle pedestals (Reference)

Would like to do

  • Figure out drift chamber alignment
  • study matching to single FCAL blocks
    • not that important
  • detailed tagger energy calibration
Beam energy reconstructed with exclusive rho events
  • better calibration of high energy FCAL showers

Which skims to use

We changed several things about the skimming during the run, since that was the first real physics run. So I suggest looking at the skims from the recent recon launch:

  • /mss/halld/RunPeriod-2017-01/recon/ver04
  • FCAL
    • skim_pi0fcal/
    • FCAL-LED/

FCAL plots

pi0 mass for inner blocks in run period 2017-01 (run 30730) - 25 April 2022 (pdf)

pi0 mass for inner blocks In run period 2017-01 (note that these plots were made using the pi0 skims, whereas the above plots were made with the full raw data, so ignore this plot!! the pi0 skims explicitly rejected in the inner FCAL layers)- 20 April 2022
