keyword=hana comments IIINext comment: right arm, S1-1L seems to be missing at ADC input. Should
be checked at next hall entry. Same effect was seen earlier today by M Jones
in espace analysis. See figure 1, observe 0 AVG adc PH for channel six,
plane 1. Note it is not HV since scaler is counting and TDC spectrum is OK.
.
right-arm scint TDC is a bit thin. bob recommended 100 ns minimum, and
50 ns was an absolute must-not. some of peaks are around 60 ns. i have
delay spools in counting house if experts decide these need to be delayed.
see figure 2.
