Run 1-10 Test

14 September 2017

Run 11 Start 18:16 (CERN time)

Faults:

adc#2 7,8 missing segments (n+n side dE)

adc#3 19 low gain (p+n E)

some strips have no noise but maybe that is OK.

Run 12 Start 11:50

Pulse switched on halfway through

Run 13 Start 12:08

Pulser on

ADC spectra:

#1 ch0 bad resolution (also pulser)

#2 ch7 ch8: no alphas, pulser there

#3 ch0 low gain, ch24 low resolution

#4 ch 7 low gain only for alphas (not pulser)

TDC missing: ch 32,80,120,123

Not understood yet: 1mm detector has peak at ~1.5 MeV @ adc#3 ch20-30 (with ALL alpha events when visible , 24 looks very distorted); not visible in ADC#4 (n+n) no alpha in ADC#6 although segment.
