Included waves for all 12 FEEs
FEES 1, 5, 9 all show this HF noise on it, and are all located at the top of the AIDA mount.
Connections: HV from DSSD (-ve) is in FEE9 |

Fri Aug 9 12:33:14 2019, NH, Aida Test 9/8/19 - FEES 1-6
|
The water issue has been resolved - merely incorrect temperature guages (replaced). Water is 20 C as required.
S4 conditions at 13:12 CEST
26.5 C / 47.2 % / Td = 14.3 C |

Fri Jun 28 15:05:49 2019, NH, Aida 28/6/2019 - WATER OFF
|
The humidity sensor hasn't reported humdities under 90% yet. In order to try and help dry the pipes and turn AIDA the water has been turned off the
weekend.
Sunday temperatures might reach 40 C which means it may struggle anyway. |

It occurs to to wonder if there is now water inside the modules. If the metal of the cooling plates is damp on the outside then it is safe to assume
there is water on the inside too . Can I suggest that one of the modules is dismounted, disassembled and checked?

ASIC 1 on FEE9 was not producing signals.
A new HDMI cable was installed but still no signals.

HT cable shielded, HT of upstream AIDA from iseg, HT of downstream AIDA from CAEN. Both channel 0 and 1 of CAEN are on, even though
there is just one channel connected. During this test, some parallele tests are being done on BB7 Mesytec. In general, middle tile: detector disconnected
from preamps but preamps connected on the other side. Right tile: detector connected to preamps, cable shielded but preamps disconnected on the other |

Tue Oct 19 16:17:49 2021, OH, AIDA-gsi server to centos 7
|
Following advice of CU have updated the server to centos 7.
To do this a new 500GB SSD was purchased and installed in the enclosure and a clean install of centos7 was installed to this.

Wed Feb 16 10:32:52 2022, PJCS, AIDA software changes and some suggestions
|
The Pi console monitor program now outputs a full date/time to file for each line of report.
The System Wide Checks has been upgraded to include a check of the PLL lock monitor counters. A baseline is taken when the software starts, or
at the users command, then subsequent operation of the command compares the current counter value with the baseline. There are two PLLs on the pcb, LMK3200, |

Yesterday we spent time essentially performing a dry run to get AIDA DAQ and bPlast into the time sorter, there were some issues with the AIDA mbs PC
x86l-119 which was related to some boot issue, it was booting to a newer version of debian while the Relay for AIDA to MBS is on an older version (scratch)
(the machine is quite old). We spent a bit of time getting the thresholds correct for each of the ASICs. In the end we just elected to have a blanket level |
