HGTD production progress:
- IHEP Batch 1 (50 wafers): IT done

- Batch 1.2 (50 wafers) on its way
- Report at the HGTD week

- Batch 2 planned on 15 March

 

General TODO:
- Ask CNM about high-fluence LGAD status (Salva)

- Ask Marco Ferrero about FAST32 status

- Check MP QT form is in GLANCE

- Contact DELVOTEK

- 3d paper feedback

 

HGTD week:
- IT report
- SQC report
- check annealing

PQC:

SQC:
- \\F9silab05\silab - disk storage\Measurents\Projects\ATLAS-HGTD\Production\automatic_probe_station
- Irradiated to 1e14:
    - 1A, 1B1, 2B2
    - Measure V spread at 95 uA
    - Measure cold

Annealing:
- 10240 min total done, aim for 10-20 kmin total
- incident with 40°C CV samples - annealed to total 30 kmin (next step 80 kmin)

Database:

IT:
- Batch 1.1 done, two suspects remeasured and improved
- Sr90 with two QCTS (incl B7-18), charge above 18 fC at 550 V
- Investigate fluence
- Ship samples to UNM
- Check results by Sbrizzi

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

Flex Tails:
- no news

Irradiations:
- Leuven ion (EUROLABS until Aug2026)
- Cyric QCTS - next irradiation in June
- Birmingham 24 MeV (NIEL factor 2.2): clarify sample preparation
- Krakow 60 MeV

Hybrid tests:
- Noise dependence on threshold checked (no dependence)
- TODO TCT interpad-gap tests

IME-3D:
- Receiving more samples
- Irradiated 2 samples to 1e15
- Ship samples to Gordana

Publications:
- HPK HAB version 4 - need to implement comments
- Mixed
- 3D - awaiting collaboration comments
- HGTD hybrid jitter
- Trento 3d project talk

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 working on recreating Santander results
- Oct 2025 SPS 
https://docs.google.com/spreadsheets/d/1gXOXmDh_rMZvVni9Ns_o9tcRdI506K8smWYKMCjrMm8/edit?gid=0#gid=0

 

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
