We have powered the CCAL up after holiday break. All channels are operational.


 1. FADC scalers and signal waveforms induced by an LED pulser are shown in  Fig. 1 - Fig. 3. 

HVs for all channels were set to 800 V, LED pulser rate - 1 kHz, LED voltage - 29 V.

run 60103

2. We tuned time delay for the Alpha source pulser, which was set to the
TS FP trigger bit 6. Some fine tuning of this trigger is required (will be done shortly)
