 Wed Jul 23 15:56:00 2025, CC, MP, NK, Test of AIDA05 with new bias module 
|
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. |

Wed Jul 23 13:59:37 2025, CC, NK, Shielding of the snout
|
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
FWHM: 76 channels (to be compared with the 2 previous elogs 73 channels and 75 channels) |
|
Wed Jul 23 13:08:30 2025, CC, NK, Comparison of channels in the same FEE64 and ASIC 05.1
|
Biased at 100, AIDA05 connected, HT cables not shielded CAEN HT
Attachment 1: AIDA05.1.8L --> FWHM 75 channels
Attachment 2: AIDA05.1.1L --> FWHM 70 channels; peak of the pulser shifted to the right (red lines on the left: cursor for the 1.8L) |
|
Wed Jul 23 09:37:34 2025, CC, NK, Comparison pulser FWHM with/without HT and detector cables 9x
|
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 |

Tue Jul 22 18:00:45 2025, CC, NK, MP, FWHM aida FEE
|
AIDA05 completely disconnected, all the others FEEs64 are fully connected
Attachment 1: aida05, FWHM= 95 ch, 63 keV
Attachment 2: aida15, FWHM= 108 ch, 74 keV |
|
Tue Jul 22 17:00:26 2025, MP, CC, Status
|
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. |
