 Fri Nov 7 12:30:30 2025, JB, GB, MP, Pulser walkthrough for source tests. 
|
13:30 We are going to do the pulser walkthrough for the the source tests.
We are wrapping the snout in some copper first to further establish a better connection with the ground.

Thu Nov 6 12:58:09 2025, NH, 207Bi source test - data taking 6x
|
Restart AIDA
aida06 took three attempts to boot today :(
|
 Fri Nov 7 10:47:29 2025, MP, 207Bi source test - data taking
|
DAQ stopped at ~17.30 due to anydesk failure
|
|
Wed Nov 5 13:23:38 2025, JB, MP, 207Bi source test - FWHM tests 8x
|
14:10 started up the DAQ. HV and TEMPS OK.
Peak threshold with 1V pulser measured at ~ 175 ADC channels. Attachment 3.

|
Tue Nov 4 14:57:19 2025, MP, Bi207 source data, 700keV
|
- Bias and basic checks: the pulser FWHM appears to be ~170, which is the same we have obtained at the end of last week.
- Initialised the Merger and Tape server
- loading of settings: EXPERIMENTS/AIDA/2025Nov03-16.21.44 |

Tue Nov 4 16:34:47 2025, MP, NH, Bi207 source data, 700keV
|
Some FEES were not acquiring data for some reason we could not understand. We lowered the thresholds to 200 keV, then rose them again to 700 keV. It
seems they are now acquiring. We start data taking again.

Anydesk has crashed. I am not able to set it up again. I switch off bias and fees

Thu Oct 30 10:06:21 2025, MP, NH, Setup and data taking with 207Bi
|
- Initialised the Merger and Tape server
- loading of settings: EXPERIMENTS/AIDA/2025Oct29-16.11.06
- aida16 very noisy (attachments 3,4), slow comparator thresholds was risen to 500 keV, until reducing its deadtime to 0 |

Thu Oct 30 16:43:36 2025, MP, NH, Setup and data taking with 207Bi
|
Data taking and DAQ stopped now (17.40)

Wed Oct 29 14:11:01 2025, JB, MP, 207Bi source test - data taking 7x
|
15:10 MP entered and check the water pressure OK.
15:10 DSSSDs biased - OK.

The cables form the AIDA FEE64 adaptor PCB to the MSL type BB18 DSSSDs are constructed as follows

Wed Oct 29 13:01:08 2025, NH, Update of AnyDesk
|
AnyDesk was updated to the latest version that supports CentOS 7 (EOL OS)
First the YUM repositories were migrated, as the original address was offline due to EOL
|
|
Wed Oct 29 08:12:35 2025, MP, Further setup for 207Bi test
|
Inspection of side FEEs (2,6,4,8) and possible grounding improvements:
- all screws and nuts for copper connections were tightenedFee
- FEE 6 was isolated from the copper connection grounding FEE2 with insulating tape (attachment 1) |
|
Wed Oct 29 12:56:29 2025, TD, Further setup for 207Bi test
|
Remember that 'ADC calibration' refers to the setup of the fast serial output of the AD9222 Octal, 50MSPS, 14 bit ADC which generates the waveforms
- if the FEE64 is unable to calibrate all that happens is that you will not be able to see preamp output waveforms. Energy spectra will work regardless
as they use a different ADC. |
|
Tue Oct 28 12:43:38 2025, JB, GB, MP, AM, Further setup of tests for 207Bi test 14x
|
- Ch 2 and 3 of CAEN HV module changed to negative polarity, Ch 0,1 still with positive polarity
- Bias changed from the n+n to the p+n side (now Ch 2,3) - att. 1
|
|
Mon Oct 27 11:55:00 2025, JB, MP, GB, NH, Changing ground setup from 25102025 9x
|
12:55 We are going to try the follow changes to the AIDA scheme of 241012025.
- Fitting LK1 (aida01, aida14), removing LK1 (aida03, aida07, aida11, aida15) - only 1x LK1 needs to be fitted per Si wafer
|
|
Mon Oct 27 18:08:11 2025, TD, Changing ground setup from 25102025
|
19.06 Found HV OFF, DAQ GOing
DAQ STOP

Mon Oct 13 15:04:53 2025, JPB, NH, GB, MP, Dismount AIDA and realign the cables
|
We have dismounted the AIDA stack and bPlast and realigned the cables so that they can fit into the adaptors.
The plan for the next couple days is the following:

Thu Jul 24 15:50:01 2025, CC, MP, NK, Check of BB7 impact
|
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. |
