checked trigger setup for 13 GeV -> OK
checked trigger timing -> OK
trigger latency increased by 3 ns, 1 ns is due to a longer cable, additional 2 ns origin not identified
MT synchro OK, cannot anticipate S1 any further
MT, T1, T2, T3, T4 all arrive at the same time
checkde HV on trigger counters (quick HV scan) -> OK
summary
S4 added amplifier (x10) to S4 counter, HV 1950 -> 1850, threshold 30 mV -> 100 mV
V0 HV 1920 no change
V1 HV 1800 -> 1850
V1p HV 1900 -> 2000
no significant improvements in "S/B" rates |
