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. |

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.

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 |

Voltage-Current test of newly installed AIDA snout. Breakdown observed at around ~92 V. Probably caused my light leakage into the snout, will investigate |

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. |
