I have looked at the TOF scaler rates, and we have the following problems:
1. Channels 145-152 overflowing 32 bits
(group of 8 out of pretrigger board into scaler)
possible problem is oscillation in pretrigger board (incorrectly terminated?)
Sector 2, ch 17-32 (triples), Simon - please verify
2. Channels 99, 100, 101 and 102 HOT (x5 normal rates)
possible light leaks
what does the ADC and TDC spectra look like?
Sector 1, ch (3,4),(4,5),(5,6) and (6,7), Simon - please verify
We should check item 1. upon next access. Elton.
