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.

Bias tests of AIDA on individual wafers and in parallel. Spreadsheet can be found in attachment 1, and graphic results can be seen in Attachment 2. Summary:
Upstream detector cannot be biased in parallel nor individually. Downstream detector can be biased with positively and each wafer can individually be biased
negatively. In parallel, it was not possible to bias the downstream detector negatively as indicated by the tests below. |

Thu Jan 9 15:43:17 2025, JB, CC, MP, Timing test platform moved in
|
16:30 We moved the platform in. The system was still biased and the DAQ was still running.
The system seems to be okay, temperatures OK. Bias voltage OK 685/1 and 685/2. Two FEEs - aida07 and aida12 are receiving a lot of trigger data
items from the fast discriminator. This is already a bit worrying. 685/3 |
