Steps in Calibration

  1. Remove 4ns ADC hardware offset (pass 1)
    1. Run reconstruction with BCAL_TDC_Timing plugin to produce the BCAL_TDC_Offsets/Deltat_raw/ histogram
    2. Run analysis script over output
      • script for single run is /home/dalton/gluex/BCAL/monitoring/macros/extract_ADC_Dt_Zcorr.C
      • /home/dalton/gluex/BCAL/monitoring/macros/monitor.py --adc4ns can be used to run over all runs
    3. Load constants to CCDB table /BCAL/ADC_timing_offsets using python macros/commit_CCDB.py -d output/ADCendDt/correction/ --adc
  2. Remove 32ns ADC hardware offset (pass 1)
    1. Set CCDB table /BCAL/TDC_offsets to 0
    2. Run reconstruction with BCAL_online plugin to produce the /bcal/bcal_Uhit_tdiff_raw_ave histogram (pass 1)
    3. Run analysis script over output
      • script for single run is /home/dalton/gluex/BCAL/monitoring/macros/extract_Uhit_tdiff.C
      • /home/dalton/gluex/BCAL/monitoring/macros/monitor.py can be used to run over all runs
    4. Load constants to CCDB table /BCAL/TDC_offsets using python macros/commit_CCDB.py -d output/tdiff/TDCcorrection/runs/ --tdc -v
  3. TDC timewalk correction (pass 2)
    1. Prerequisites:
      1. Remove 4ns ADC hardware offset
      2. Remove 32ns ADC hardware offset
    2. Run reconstruction with BCAL_TDC_Timing plugin
    3. Run analysis script over output
    4. Load constants to CCDB
  4. Position from end time-difference (pass 2)
    1. Prerequisites:
      1. Remove 4ns ADC hardware offset
    2. Run reconstruction with BCAL_TDC_Timing plugin
    3. Run analysis script over output
    4. Load constants to CCDB
  5. Calibrate the point time offset from tracking (pass 2)
    1. Prerequisites:
      1. Remove 4ns ADC hardware offset
    2. Run reconstruction with BCAL_TDC_Timing plugin
    3. Run analysis script over output
    4. Load constants to CCDB
  6. Attenuation length and gain ratio (pass 3)
    1. Prerequisites:
      1. position calibration (pass 2)
    2. Run reconstruction with BCAL_attenlength_gainratio plugin
    3. Run analysis script over output
    4. Load constants to CCDB
