Description

All 25 BBCal trigger sums are read out by two FADC modules which are situated in a different crate than the one used by BBCal PMT signals. Mark suggested me to look at the ADC time correlation between the highest energy block of BBCal cluster and the corresponding trigger sum. The events at the secondary peak were correlated in the same way as the ones in the primary peak. This would suggest that both the crates experienced the shift in time (~12ns) for same events, which would make sense if the delay is coming from the Trigger Supervisor itself.
