20:00 Taking over from CB
20:33 Doing full checks.

|
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:
|
|
Wed Jun 5 08:34:47 2024, JB. AM, MP, MY, Detector bias tests 14x
|
We are trying to bias each system on its own and in sequence biasing each other detector system to see the interdependence.
HV OK. TEMP OK. Attachment 1 &2. |
|
Thu Apr 11 08:27:21 2024, JB, TD, 11 April noise tests 48x
|
TO-DO for 11.04.2024
- Try bringing bPlast drain wire ground back to the PSU ground for PN 300 and R&SRMP4040.
- Recheck the downstream
detector bias and ground scheme.

09.52 DAQ continues file S100_alpha/R5
note merger not functioning correctly due to aida03, aida04 & aida09 out of WR sequence
|
|
Mon Mar 11 15:19:44 2024, JB, NH, Priyanka, Michael Armstrong, Helena Albers, To Do: AIDA PCB tests
|
To do:
1) Disconnect ribbon cables from p+n junction FEE64 adaptor PCBs of upstream DSSSD, apply c. 100V bias and check leakage current is zero
i.e. eliminate shorts in PCBs |
|
Thu Mar 14 13:00:23 2024, JB, NH, MA, AM, GA, Mounting and biasing DSSD 2
|
new Downstream DSSD2: 3208-2/3208-5/3208-8
Covered with black cloth. |
|
Thu Mar 14 12:13:17 2024, JB, NH, MA, Mounting and biasing DSSD 1
|
Upstream bPlast mounted
new Upstream DSSD: 3208-2/3208-5/3208-8
|
|
Wed Mar 13 13:02:19 2024, JB, NH, HA, MA, DSSD 1 biasing tests
|
Dismounted Snout and biased DSSSD1 channels
leftmost waifer working
middle waifer reaches 90V then current ramps up |
|
Thu Mar 7 15:15:29 2024, JB, NH, CC, AIDA HV Bias Test IV Curve

Voltage-Current test of newly installed AIDA snout. Breakdown observed at around ~92 V. Probably caused my light leakage into the snout, will investigate |
|
Wed Mar 27 14:22:35 2024, JB, NH, Installing FEE64s of DSSSD2 14x
|
Mounted on frame:
DSSD 1 (Upstream) : 3208-2/3208-5/3208-8
DSSD 2 (Downstream): 3208-3/3208-21/3208-22 |
|
Mon Jun 3 14:40:34 2024, JB, NH, 03 June 2024 10x
|
15:40 reseated FEE64s adaptors of aida01, aida09, aida13 & aida16.
TEMP OK. HV OK. System wide checks all passed excl. aida07 ADC calibration, see attached.
Histograms and rates look same as previous, reseating aida01 seems to have worked. aida16 still unhappy. |
|
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

Day2:
10:14 we set up the detector with the pulser in BB7 and started biasing the detector and setting up the DAQ. Water flow and temperature check, |

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 |
