DAQ was found yesterday with none of the FEEs reporting any good events on any FEE - attachment 1
Temperature menu is still responsive and all FEEs report a temperature
Looking at the white rabbit timestamps aida09 has a gibberish timestamp - attachment 2

Disconnected test - pulser from aida08. Noise conditions improved slightly, probably less pulser events. (Attachments 1 & 2).
We recabled the dew point sensor and flow sensor for the water supply interlock to the FEE64s. When we tried to power up the interlock box, the
PSU (charging block) LED was blinking indicating an internal power instability. We then plugged each of the sensors out and into the interlock box and |

At 20:15, We lost connection with AnyDesk.
Liliana restarted Anydesk on the AIDA DAQ PC. All seemed fine on AIDA DAQ but there was a more generic issue on the main DAQ, possibly the timesorter.
Helena restarted all after ~30mn and it's all working again now. |

This elog is the first reliable. Before, the histograms have not been zero'd
Each test are done and compared for AIDA05.1.8L, compared with the pulser (caracteristics, see attachment1)
Test 1: with HT cables shielded |

Wed Jul 23 17:02:22 2025, CC, NK, Comparison of channels in the same FEE64 and ASIC 05.1 and with AIDA13.1.8L 8x

BB7 is still connected but not biased (same configuration as the previous elog). The channel of the CAEN power supply #0 is connected to ASIC08 and biased
at 100V. The channel of the CAEN power supply #1 is disconnected but still biased at 100V. AIDA04 (chained to AIDA05) is biased via a shielded cable to
an iseg NHQ 246L power supplied, biased at 101 V with 16 uA. |

HT of upstream AIDA from iseg, HT cable shielded, 100V, 17 uA. HT of downstream AIDA from CAEN, AIDA#0. Both channel 0 and 1 of CAEN
are on, even though there is just one channel connected. DEGAS platform closed. The crates of BB7 and bplast have been put to the ground of the AIDA's
