Event generators (should be in the PrimEx analysis directory)

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

4. 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)

5. Double Compton Generator (Pavel)

6. 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)

2. Recalibrate CCAL (non-linearity corrections) -- Drew

Adjust tagger energy scale -- Sasha

3. FCAL calibration

• Do we use official GlueX cluster reconstruction or an Island algorithm ?

  How many calibration versions (run periods) we need ? Check with LED data (Chandra)

4. FCAL dead/suspicious channels in the CCDB (Chandra)

• exclude channels from MC and reconstruction

MC simulation (GEANT) =

1. Adjust position of the CCAL according to the survey data

2. Adjust position of the FCAK according to the survey data

3. Adjust CCAL energy resolution
