SondaIntraoperatoria.jpg

• Intraoperative probe
  • First working assembly succesfully completed
    • Assembled by Sabino/Giuliano
    • Bonded by Sabino/Giovanni 
    • Verified by G. de Robertis
    • Sylgard to protect the wires by Giovanni
    • MOSAIC board retaken from N. Mazziotta (4 boards available in total: 1 for didactical purpose)
    • New firmware to be shared by G. de Robertis
    • Next steps: load the new firmware and verify the sensor performances in lab, calibration and source
    • Next to next steps: measurements using radiotracer at ITEL, to be defined
  • Design of the current probe prototype encoded in dedicated GEANT4 simulations to be used for future data/sim comparisons
    • For example, simulation of the future measurements at ITEL and comparison of the results to those of real measurements
    • Acts as a validation to extend the simulation to more complex scenarios, not easily to reproduce experimentally (e.g. full-body simulations)
  • Worth to start asking for a design of a stick to be used to handle the probe, which allocates the USB-C cable
• Stack A9
  • Carrier board delivery in one month
  • Bonding loop shape defined, using 100 um thick ALPIDE
  • First A4 using ALTAI (50 um thick) to validate the loop shape 
  • Next steps: 
    • Full A9 ALTAI (50 um) bad assembly
    • (once board become available) A2 or A4 assembly with mid quality sensors for board validation
    • (if everything verified) full A9 assembly with good quality sensors
    • Measurements with radioactive source + Measurements at beam facility (under investigation Bergen)

12:20 → 13:00 AOB (planning of conferences, ITS3 mechanics, ALICE3, SVT, … )

Speakers: Angelo Colelli (Istituto Nazionale di Fisica Nucleare), Domenico Colella (Istituto Nazionale di Fisica Nucleare), Domenico Elia (Istituto Nazionale di Fisica Nucleare), Francesco Barile (Istituto Nazionale di Fisica Nucleare), Triloki Triloki (INFN Bari Italy)

• ITS3 WP4/WP5
  • BBM6 assembly completed and delivered to CERN on week 8
    • Possible contribution to the BBM6 measurements by Triloki, to be confirmed and agreed
  • Power dissipation studies using L0 heaters on mandrel --> Results will be shown next week during WP5 meeting
  • Next activities:
    • Working super-ALPIDE assembly will start next week
      
      
• SVT
  • First L0 assembly (double-sensor) succesfully completed on week 6
  • New sensor handling tools (common to ITS3) produced 
  • New support structures gluing tools produced
  • Next activities:
    • New L0 assembly, still using wafer remnance L0 size, using new tools will start during next two weeks
