Topics Discussed

DUT Overview

• First batch approved

  • Samples → mounting, wire bonding, testing before TB → Iskra

• W5 V1/V2 TW5 (standard 2 × 2 pixels)
  or W5 V2 TW1/2/3 → 0E15 neq/cm² (Zurich + CERN)

• W5 V2 TW4/6 → 1.5E15 neq/cm²

  • Measurements at different sensor tilt angles together with the non-irradiated DUT

• W5 V2 TW1/2 → 2.5E15 neq/cm²

• W2 V2 TW1/2 → 2.5E15 neq/cm²

  • Possibly different bias voltage points

Hardware & Equipment

• 25 × 100 µm² CROC to be installed on Monday (Jordi + Antonio)

• 3 LV and 2 CAEN HV supplies (e-pool – done → Marcos)

• Cables + splitter (Leena; splitter I/O (3) found at CERN)

• Irradiated wire-bonded samples already at CERN from previous test beams (to be checked)

• 2 telescope planes missing (telescope to be checked before TB starts) → Iskra + Marcos (next week at H6)

• Chubut boards (Leena + Iskra)

• Scopes → will use only one  for triggering 

• 2 × 5 GS/s CAEN digitizers

  • One already at CERN (JSI office)

  • One from Santander

• Cold box → same status as before

• Newport nano-stages → provided by LHCb (Victor Coco)

---

Schedule

• 1 week + 1 week (parasitic user)

• First week: running with TI-LGADs

• Second week: + 3D IME structures (2 samples and channels in the CAEN digitizer)
