19.45 Remote system check

      DSSSD bias & leakage currents OK - attachment 1

      FEE64 temperatures OK - attachment 2
       aida02 ASIC temperature often reporting zero but sometimes a sensible value - presumably PT100 fault

      ADC data item stats - attachment 3
       all FEE64s at high/very high rates - only 3x of 16x FEE64s < 100k
       ASIC settings per aida01-aida04
        p+n FEE64s slow comparator 0xa, n+n FEE64s 0xf cf. 0x64 used for previous tests by Nabil? 

      per FEE64 Rate spectra - attachment 4

      per FEE64 1.8.W spectra - 20us FSR - attachments 5-6


19.55 Switch to safe state (FEE64 power OFF, DSSSD HV OFF) overnight as appears to be unattended/not monitored overnight.

      Tomorrow I would suggest resuming tests (using slow comparator 0x64) and checking per FEE64 pulser peak width for comparison with previous tests by Nabil. If 
unable to reproduce previous tests (or previous AIDA performance) you will need to check setup/reduce noise to be able to perform measurements using the 207Bi source.
