List of changes

These lists are giving the run ranges where the FCAL hardware was not changed.

Hi Igal,

If I see this correctly, the CPP run period was June 08 - August 16. During this time I could find only one PMT change:

07/23/2022 https://logbooks.jlab.org/entry/4019114 (one PMT changed)

This change was done right before the run: 06/06/2022 https://logbooks.jlab.org/entry/3999544

Monitoring results

What is currently in the calibration variation=cpp_fcal_cal

  • Pedestals for each run
  • Bad blocks for each run
  • Gain & Time calibrations (underway)
  • Energy calibration (not yet there)

What is currently in the default variation

  • For the energy calibration (empty target periods used period 1 table)
    • period 0: 100408-100845
    • period 1: 100961-101010
    • period 2: 101011-101044
    • period 4: 101076-101154
    • period 8: 101255-101336
    • period 11: 101439-101587

NB: the period in this section does not match the period in section "Period" but matches the period in section "Gain matching calibration plots". And the period for energy and time is not the same!

  • For the time calibration
    • period 1: 100408-100960
    • period 2: 100961-101587

Periods

The periods in BOLD are calibrated i.e. have a pedestal and gain tables. Each period corresponds to constant FCAL and/or experimental conditions.

  • period 0: 100408-100490
  • period 1: 100491-100960
  • period 2: 100961-101010
  • period 3: 101011-101044
  • period 4: 101045-101074 (empty target)
  • period 5: 101076-101154 (some blocks set to 1 in block_quality)
  • period 6: 101164-101166
  • period 7: 101167-101254 (empty target)
  • period 8: 101255-101336
  • period 9: 101337-101392 (Hall B half-wave plate in)
  • period 10: 101393-101402 (Hall B half-wave plate in & empty target)
  • period 11: 101403-101438 (empty target)
  • period 12: 101439-101529
  • period 13: 101530-101535 (Hall B half-wave plate in)
  • period 14: 101536-101587
  • period 15: 101597-101622 (empty target)

This map is done for each run number by combining the info collected by analyzing the LED and pi0 skims.
