14:52 Attachment 1 shows low energy spectra. AIDA06 shows strange baseline, possible double-hit?

15:06 Systems checks fine.
      Master clock failed (no master clock)
      all checks passed
      memory checks all around 38k as normal

      Attachment 2: Temperature check all normal except aida01 virtex temp slightly over 65 degrees

      Attachment 3: Good event stats seem normal except downstream SSD seems to be high around 200k

      Attachment 4: leakage currents seem normal at expected values

15:16 Merger working for all FEEs
      tape server is on but no storage
      data rate is around 25 MB per second (high but consistent with the high stats of downstream SSD)

ASIC controls checked and are all OK

ALL FEEs in downstream SSD are high

16:21 included low energy pulsar peaks (Attachments 5 & 6) and waveforms for all FEEs (Attachments 7 & 8)

16:25 included rates, note not to common scale in y (attachment 9)

ASIC settings file 2019Dec19-16.19.51 but some others are on 2019Oct31-13.24.23
  Did not seem completely reproducible?
  We carefully checked all the individual FEE and ASIC settings, and they are all the same (except shaping reference), with NO 0xad

Now we made sure they are all using 2019Dec19-16.19.51 (which we had saved first on a good one)


19:15 Update

There is a safety interlock box in S4 to monitor humidity, dew point, temperature, etc for safety.  
It had a loose solder connection, and when someone moved it out of the way, the interlock was tripped.
After some debugging, the interlock is now in a more stable condition, but a lot of power was cut from AIDA systems

One unusual thing was that one of the RPi systems got a full /var/messages (or similar) and ate all the available disk space 
  This meant that ssh -X (to, e.g., activate putty) could not work, giving a permission denial error (ssh connection was allowed, but not X11 forwarding)

Now we have brought back up the AIDA systems and should run through the checks

Most system checks look good (except some calibration errors)

Temps were running high until we reloaded the ASIC settings, then the temperatures began to cool

Bias and leak currents attached as #10

Temps as #11

Stats as #12

19:50 Started writing to disk so that we can do an implantation depth profile. Will analyse near online using AIDASort.

21:45 Stopped writing to file -> Runs where AIDA thickness were investigated corresponds to R3_62 to R3_72
      A rough method using the rates histogram was used to judge roughly when depositing in each histogram - see attachment 12 (Stopping in 2)
      Can match to the FRS files to work out degrader thickness with timestamps (File stopped at Mon 09 Mar 2020 09:44:51 PM CET

21:51 AIDA running to no storage again
