> > 12.08 DSSSD bias & leakage current - attachments 1-2 > CAEN logger program crashed sometime this am - now restarted > DSSSD #2 and DSSSD #4 OK - DSSSD #4 stable since c. 03:00 20.4.25 > DSSSD #1 and DSSSD #3 remain high > All DSSSDS show effect of ambient temperature transient in CRYRING hall > > CRYRING vacuum and temperature - attachments 3-4 > > 14:40 > > FEEs started up. Background run started. Pulser running in the at 1HZ, amplitude is 9000. > Note aida03 and aida04 set to MEC due to high rate >100k. This resulted in data rates ~3MB/s. Slow comparator thresholds set to 0x64 (1 MeV) > System checks OK. AIDA16 and ADC calibration check clock status fails. > Run 10 started. > Attachments 5,6,7,8,9 from start of run. Waveforms, ADC data items statistics, New merger, Tape server respectively. > Will continue to monitor during the day until tonight when I will turn off the FEEs again. > > Run stopped. > Noticed spike in leakage current for all detectors. > This coincides with change in vacuum around the ring. Some operation is ongoing, all FEEs off, detectors off. > See attachment 10 for leakage currents. > > Vacuum gauge in section 9 is back on to allow for ring interlocks. > > 29/04/25 > > Turned the FEEs on to check if aida08 is still connected to the coolant loop. Temperatures in normal range after startup. FEEs turned back off for now. Encoding: HTML ELCode plain Suppress Email notification
