<p>Disconnected the adaptors with the detector.</p>
<p>Added the adaptors with the kapton cables only attached.</p>
<p>Connected the pulser outputs ( pos and neg ).</p>
<p>nnaida11,13 & 14 : Stat spectra are normal. Rates are 10k to 16k</p>
<p>nnaida12 has normal stat spectrum with ASIC3 only showing channel 5.</p>
<p>Power cycle and re-try.</p>
<p>No different. <br />
Suggest change the Mezzanine on nnaida12 and ask for the ASIC to be replaced..... maybe visible signs of problem ?</p> |
