DSSD4 has been biased to 100V in steps of 5V from 60V. It was previously stable overnight at 60V - attachment 1

Will keep an eye on it but looks OK at the moment. Current bias and leakage current - attachment 2

I have reset DSSD4 FEES (13,14,15,16) to the LEC and lowered the thresholds to be in line with other FEES.

Current slow comparator threshold for all FEES is 0x14 (200 keV).

Attachment 3 shows current ADC data items statistics.

Started a new run 51 with no beam and no target. Access to the cave is allowed.

Current data rate is 800 kB/sec.

All statistics and histograms in aida zero'd
