- Positive logic
- NIM logic
- PMT signal
I think it is caused by generator’s big internal delay => signal goes away from the time window for counting
Finding the proper threshold and the ratio of charge/ADC counts, taking real(?) data, and analysis the data.
- Board clock counts for the fastest hit between the channels (It has random reference position in time dimension. One count matches with ~9.4ns)
- Time difference from above time to the time of firing discriminator in ¼ clock count units for each channels (If there were no fire, it shows 0. The minimum quantized value is ~2.5ns)
