Production progress:
- 50 wafers will be brought to IJS next week
- Positions 5, 30 and 43 will be packed into bags and irradiated

- Positions 10 and 48 will be placed into large gel-paks

- Small gel-paks to return to IHEP

- A batch of another 50 wafers arriving around the new year (to be tested by first half of Feb)

PQC:

SQC:
- \\F9silab05\silab - disk storage\Measurents\Projects\ATLAS-HGTD\Production\automatic_probe_station
- To irradiate to 1e14:
    - 1A, 1B1, 2B2

Annealing:
- 5120 min total done, aim for 10-20 kmin total

Database:
- Guilherme's scripts for Sr90 upload tested, testing to see results in Grafana

IT:
Wafer radiation hardness class (A, A'?, B...) to be discussed on Monday sensor meeting

Timing:
- Voltage steps 400, 450, 500, 550 V, (600 V)

Flex Tails:
- no news

Irradiations:
- Leuven ion (EUROLABS until Aug2026)
- Cyric QCTS - next irradiation in June
- Birmingham 26 MeV

Hybrid tests:
- Unirradiated laser tests done with Theo (good job!)
- TODO TCT interpad-gap tests
- Submit ATLAS QT form
- Climate chamber replacement
- Asking Delvotek to convert bond program files

IME-3D:
- Receiving more samples
- Irradiation plan 5e15, 1e16 (reworking challenging)

Publications:
- IT paper published
- HPK HAB version 4 - need to implement comments
- Mixed
- 3D
- HGTD hybrid jitter

3D CNM:
- 1-x (square single), 2-x (hex single), 4-x (hex 5x5), 5-x (square 5x5)
- Gordana requesting more samples
- Need an internal database of samples and their location, fluence

AIDA TI-LGAD:
- April 2025 analysis pending
- Oct 2025 SPS testbeam ongoing
https://docs.google.com/spreadsheets/d/1gXOXmDh_rMZvVni9Ns_o9tcRdI506K8smWYKMCjrMm8/edit?gid=0#gid=0

- TODO laser tests to understand channel to channel coupling and guard ring effects

 

Thin LGAD (Ex-Flu)
- Received 15, 20 um thick LGADs
- Todo timing unirradiated

 

AC-LGAD:
- IHEP shipment first TCT done with Chubut

 

CNM overdoped LGAD:
- In the last stage of processing

 

CiS LGAD:
- Production ongoing

 

Summer student projects:
- DC AC TCT for defect studies (start Top-TCT IR with W317, next irradiated, next E-TCT). Try also red light
- weighting field simulation in HGTD pixel corner
- 3d in photovoltaic mode
- MP exploring open source TCAD software
