|
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
structure (cupper sheet) |

Thu Jul 24 13:36:34 2025, CC, MP, NK, AIDA05 connected and disconnected compared to AIDA09 10x
|
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 |

Thu Jul 24 10:28:04 2025, CC, NK, MP, 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 an unshielded
cable to an iseg NHQ 246L power supplied, biased at 100 V with 15 uA. |

|
Attachment1: AIDA05.1.8L when AIDA05 connected, biased at 101 V with shielded cables. 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. |

Wed Jul 23 15:04:26 2025, CC, MP, NK, Test of AIDA05 with BB7 connected to Mesytec but not biased
|
Attachment1: AIDA05.1.8L when AIDA05 connected, biased at 100 V with not-shielded cables, after the DEGAS platform has been closed, the 2 tiles of BB7
have been connected to the mesytec preamps. BB7 is not biased. The mesytec preamps have been fully connected and supplied but 6/8 black cables are not
connected on the other side. 4X and 4Y are connected to the 2 FEBEX cards. |

Attachment1: AIDA05.1.8L when AIDA05 connected, biased at 100 V with not-shielded cables, CAEN HT, after the base of the snout (screws) has
been connected to the ground via cupper sheets

Test with shielded HV cables for both detectors.
The FWHM for ch1 is now 184 ch.
Yesterday cables for cards 5, 6, 10, 11, 12, 14, 16 were partially connected (only 1 out of 2 flat cables was in), now both are connected. |
