PQC:
- van der Pauw measurements: Ke220 current source + 6517 Voltmeter configuration, manual scan: n+ resistivity same as CERN, pstop bad contact, AL not yet checked
 

Database:
- Check with database managers how to upload Sr90 measurements

IT:
- Test HV sparking in hybrids (parylene coating required or not?): check irradiated sample activity

Timing:
- Voltage steps 400, 450, 500, 550 V, (600 V)
- generate charge vs Ileak plots and add data into the database
- oscilloscope sent to service (open service order)
 

Long term stability:
- USTC samples received (check also for Co60 mounting)

Flex Tails:
- Waiting for Elgoline quote
- Request samples for TID irradiation
 

Publications:
- Autorship policy for ATLAS HGTD: projects funded with CERN core money have FIRST AUTHOR + FULL HGTD author list
- HPK HAB first version completed - BH submitted comments - check what KEK (Koji Nakamura) has presented so far
- IT QC test paper: first version completed. 
- Need an HGTD-IT ATLAS note 
 

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)
- 3D RD50 samples: AidaInnova testbeam (DESY Feb2024, SPS Jun2024 Aug2024 Oct2024). Analysis meeting: AIDAInnova 15 March
- AIDAInnova testbeam analysis: Feb2024 data (run278) - telescope alignment done, produce charge spectrum, calibration, efficiency

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)
- weighting field simulation in HGTD pixel corner
- 3d measurements with TCT+Sr90 (use LGAD for time reference)
- 3d in photovoltaic mode
