<p>Run 1-10 Test</p>
<p><strong>14 September 2017</strong></p>
<p><strong>Run 11 </strong>Start 18:16 (CERN time)</p>
<p>Faults:</p>
<p>adc#2 7,8 missing segments (n+n side dE)</p>
<p>adc#3 19 low gain (p+n E)</p>
<p>some strips have no noise but maybe that is OK.</p>
<p> </p>
<p><strong>Run 12</strong> Start 11:50</p>
<p>Pulse switched on halfway through</p>
<p><strong>Run 13</strong> Start 12:08</p>
<p>Pulser on</p>
<p>ADC spectra:</p>
<p>#1 ch0 bad resolution (also pulser)</p>
<p>#2 ch7 ch8: no alphas, pulser there</p>
<p>#3 ch0 low gain, ch24 low resolution</p>
<p>#4 ch 7 low gain only for alphas (not pulser)</p>
<p>TDC missing: ch 32,80,120,123</p>
<p>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.</p> |
