• Environment variables /group/halld/Subsystems/trigger/set_env

1. (source set_env)

• Some plots from the event analyzer. A 'typical' example of a cosmics event triggered with a small scintillator (cosmics particles come from the left).

FADC readout: RAW window mode (100 samples)

Histograms:

1. FADC pulses: 16 channels on the downstream side (FADC1), 16 channels on the upstream side (FADC2). X axis - samples, Y - fadc amplitude

2. TDC hits (time): 12 channels (downstream) + 12 channels (upstream)

• 

  FADC1 downstream side

• 

  FADC2 upstream side

• 

  TDC hits downstream

• 

  TDC hits upstream

4+4=8 hits in 2 FADCs and 4+4=8 hits in the TDC (on both sides of the BCAL)
