 Tue Mar 12 16:16:49 2024, NH, TD, JB, HA, Summary of DSSSD Biasing 12.03
|
DSSD#1 undergoes a breakdown at 90V, two of the three wafers show this
- The adapter PCBs themselves have no breakdown at 100V, indicating the issue is internal to the snout

|
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 |

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. |
