keyword=BB Cerenkov discriminator calibration
I measured the signal amplitudes at the trigger discriminator and at the
TDC discriminators.
In both cases a 1 photo-electron pulse was roughly 50--75 mV in amplitude.
Right now, the TDC (ie. individual PMT) discriminators are set to -300mV,
or 4--6 photo-electrons. (The trigger discriminator is remotely
controllable.)
