- Have to be compiled with the evio libs
- raw_check.C
- Opens the root file and plots some data quality histograms
Compile & Run
- Copy /group/halld/Subsystems/trigger/bcal_beam
- Copy /group/halld/Subsystems/trigger/coda
- Environment variables /group/halld/Subsystems/trigger/set_env
- (source set_env)
- make (in bcal_beam dir)
- bcal_beam file_name.evt.0
- file_name.root will be created
- To analyze root file:
- root
- .x raw_check.C
Examples
- 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)
