PQC:
- Fill the Vgl (?)/Vbd results into the production spreadsheet

SQC:
- 5 A + 5 B1 (low Vgl) + 5 B2 main sensors received & tested with automatic probe station
- \\F9silab05\silab - disk storage\Measurents\Projects\ATLAS-HGTD\Production\automatic_probe_station
- No correlation with CQC results (15C x 1R + GR) on B1 & B2 sensors
- Need to engage with IHEP

Database:
- Test Guilherme's scripts for Sr90 upload

IT:
- 16 wafers OK, 1 (W9) borderline (Gain 2.6 < 2.7 thr)
- Todo Sr90: W9, W with highest/lowest/medium Vbd preirradiation
- USTC W7 unirradiated Sr90 tests do more if possible
- Mixed irradiation: samples n+annealed, todo CV/IV, Sr90

Timing:
- Voltage steps 400, 450, 500, 550 V, (600 V)
- Oscilloscope operation still unstable

Flex Tails:
- no news

Publications:
- IT paper submitted
- HPK HAB version 4 - need to implement comments

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

AIDA TI-LGAD:
- April 2025 analysis pending
- Samples prepared for Oct 2025 SPS testbeam

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

 

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

 

Summer student projects:
- TPA-TCT with RD50 CNM 3d / IHEP 3D - Ajda Osterman
- DC AC TCT for defect studies (start Top-TCT IR with W317, next irradiated, next E-TCT). Try also red light - Marko
- weighting field simulation in HGTD pixel corner
- 3d measurements with TCT+Sr90 (use LGAD for time reference)
- 3d in photovoltaic mode
- MP exploring open source TCAD software

 

08:15 → 08:25 QC/QA

Speakers: Bojan Hiti, Gregor Kramberger (Jozef Stefan Institute), Iskra Velkovska, Jernej Debevc (Jozef Stefan Institute (SI)), Matic Terglav (IJS)
