Event generators (should be in the PrimEx analysis directory)

  1. Signal Primakoff
  2. Coherent / incoherent
  3. Hardonic background (generate MC samples of contributing decays)


  1. Compton with rad corrections
    • Currently have simple 'Klein Nishina' generator with 1/E energy-dependent spectrum
    • Need to implement realistic shape of photon spectrum (efficiency)
  2. Double Compton Generator (Pavel)


  1. Need to generate MC samples according to realistic run conditions (samples for each run)


Calibration

(need to finalize calibrations before we start reprocessing PrimEx data)

  1. Timing calibration for FCAL, CCAL (ST, TOF, BCAL, tagging detectors)
  1. Recalibrate CCAL (non-linearity corrections) -- Drew
  • Adjust tagger energy scale -- Sasha
  1. FCAL calibration
  • Do we use official GlueX cluster reconstruction or an Island algorithm ?
    How many calibration versions (run periods) we need ? Check LED data (Chandra)
  1. FCAL dead/suspicious channels in the DB (Chandra)
  • exclude channels from MC and reconstruction
