18/10/16 START: 16:56 18/10/17 STOP: 9:51 ROOT file: 181017_0951_BkgOverNight.root Comment: Tube 121 is noisier than the others (see fig). Issue: all the channels connected to PA3 and PA4 have twice the number of counts than the remaining channels (!?). Actually the pulser counts. Solution: This channels are from UPC tubes and are connected to pulser PB-5. We found that the threshold of external trigger was set to 1V instead to 1.8V as before and this was producing a double pulse (see photo) like triggering on the fall and rise of the trigger pulse. This happen whenever the threshold as below 1.6V. We do not understand this: the signal has +2.2V and no apparent ripple (!????). We set threshold to 1.8V and now is OK
