PQC:
- van der Pauw measurements: Ke220 current source + Ke2000 Voltmeter configuration -> will be installed in the next days

Database:
- Upload of Sr90 results --> Contact Guilherme about the progress

IT:
- Test HV sparking in hybrids (parylene coating required or not?) --> one of the hybrids survives 700 V (670 V on sensor, 30 V on bias resistor), one hybrid died at 730 V (700 V). Want to ship them to IFAE for forensics (Gamma spectrometry on Monday)
- Iskra QT final report - presentation + 2 notes (review ongoing)
- Acceptance criteria separate for IHEP and USTC -> new plots in paper draft
- 4+4 IHEP&USTC  main sensors received from RBI for Co60 (0.5, 1, 2x 1.5 MGy) -> send to USTC after Trento, plan hybridization
- HGTD week talk: IT status (accpetance criteria), LTS, sparking

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

Long term stability:
- USTC 0e14, 15e14, 2x25e14
- 15e14 was initially noisy above 300 V. Swapped 25e14 and 15e14 on DAQ boards, now both look okay (360 V & 500 V)

Flex Tails:
- Lucia prepared production sharing document

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.
- HGTD testbeam paper will require Sr90 data

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: Oct2024 - preparing poster for Tredi

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
