EM background rate studies
From GlueXWiki
Data sample:
- beam photons (no interactions inside the cave)
- collimator cave background (photon beam hallo, particles from the cave, ...)
Subdetector rates (at least one hit in the subdetector)
Beam background Cave Background
- TOF 35.9 MHz 36.8 kHz
- Start counter 1.86 MHz 1.67 kHz
- FCAL (Ecell > 30 MeV) 4.25 MHz 6.69 kHz
- BCAL (Ecell > 20 MeV) 300 kHz 1+-1 kHz
