PQC:
- van der Pauw measurements: setup with Ke220 (single measurement) works well, results same as CERN
- need to implement switching matrix (check if connecting one pad per structure together is ok)
- Residue on one of the needles - try to remove (has this been resolved)?

Database:
- Test Guilherme's scripts for Sr90 upload

IT:
- HV sparking in hybrids:
    - Ship tested modules to IFAE contact Sebastian Grinstein
    - 10 new modules received: target fluences 4e14, 8e14, 15e14, 7 x 25e14
- IRRAD QCTS received
    - CV, TCT and Sr90

Timing:
- Voltage steps 400, 450, 500, 550 V, (600 V)
- Set up multichannel system (caen)

Flex Tails:
- none

HGTD detector performance (my limited take):
- need to prepare implementation for ATLAS Athena to predict detector performance vs position & Lint (Vbias & charge)
- Input t_MC, smearing with noise and time resolution, output t_hit for digitization
- required inputs:
    - dE/dx - will try using Athena muon infrastructure which has multiple hits per track
    - Lumi profile: each MC campaign present average annual performance (HGTD performance has faster rate of change). Would be convenient ATLAS wide. Work with Data preparation group

Publications:
- Autorship policy for ATLAS HGTD: projects funded with CERN core money have FIRST AUTHOR + FULL HGTD author list
- HPK HAB version 4 - need to implement comments
- IT QC test paper: paper done in-house, now HGTD approving plots, after that HGTD paper approval
- HGTD testbeam paper will require Sr90 data

3D CNM:
- received second shipments of run 16069 - CVs in progress
- 1-x (square single), 2-x (hex single), 4-x (hex 5x5), 5-x (square 5x5)
- prepared for irradiations: 5e15 (4-x), 1e16 (4-x, 5-x), 5e15 (4-x, 5-x)
- metalization removal: 4-x, 5-x done, process some 1-x
 
AIDA TL-LGAD:
- prepared for irradiations 8e14, 15e14, 25e14
- testbeam SPS 14-23 April 2025:
    - main: V2 TR1 TW3
    - secondary: V2 TR1 TW 4,5,7,    V1 TR1 TW5
- check I-V on other V2 TR1 TW 4,5,7
- check equipment list & shifter list
 
Thin LGAD (Ex-Flu)
- Received 15, 20 um thick LGADs
- Todo timing unirradiated
 
AC-LGAD:
- IHEP shipment underway
 
Other:
- Try Edge-TCT on QCTS: polishing, optics to be explored. The goal is to measure E-field/gain, also helpful to NIKHEF/Nijmegen HGTD performance simulation (QT Petja)
 
 
Summer student projects:
- SiC TCT with RD50 CNM - 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
