      DavideP report 1m
      Speaker: Davide Pinci (Istituto Nazionale di Fisica Nucleare)
      • first draft of CSN2, ready by Friday
      • shippings:
        • M2x14 and M2.5x20 screws arrived
        • chips for Herman bought on EDH, now we need a ship from CERN;
        • need of indication of the "channel" diameter in the gas-flange to be realised by Bussetti;
      • cross-check GEM radioactivity files with Giulia
    • 09:02 → 09:03
      Elisabetta report 1m
      Speaker: Elisabetta Baracchini (Istituto Nazionale di Fisica Nucleare)
    • 09:03 → 09:04
      DavideF report 1m
      Speaker: Davide Fiorina (GSSI & INFN)

      Hardware / Mechanics
      - New source flange drawn by Antonio to hold the Tedlar window; still to be cross-checked with Filippo and Cesidio.
      - Nylon 66 structure re-machined; dry run now successful.
      - Cathode frame (Nylon 66) still slightly bent; try again to restore it, avoiding excessive heating.
      - Issue on M16 cable gland for HV cathode on PMMA: arose and was solved last week.
      - Wednesday: allocated slot for GEM stack assembly.

      Hall F / Infrastructure
      - LIME fully decommissioned; works started in Hall F.
      - SS flange for Hall F gas system must be re-done to fit LNGS workshop constraints.
      - LNGS workshop to also make an adapter for dewar wheels.
      - Hall F infrastructure: need to procure a new ~20 m cathode HV cable.

      Gas system
      - Gas system test successful; system appears gas-tight.
      - Leaks likely attributable to the LIME detector only; test will be repeated.

      Procurement / Admin
      - Nylon 66 fittings are late; no estimated delivery time, I will ping the supplier.
      - Procurement of humidity and oxygen sensors: no update.
      - Admin/procurement: Rometec affidamento + NIER PRA (LN): no updates on both.
      - Still pinging A.Ianni to fix the Polyetylene from Darkside

      Papers / Publications
      - HFO paper: feedback from Florian received; implementing changes, then submit to PubComm.
      - Directionality paper: finishing the first draft this week.

      Simulation
      - Could not meet Giulia to understand how to modify the CAD for CYGNO04 simulation; will try again this week.

    • 09:04 → 09:05
      Giorgio report 1m
      Speaker: Giorgio Dho (Istituto Nazionale di Fisica Nucleare)
      • Samuele and Rita's code on limits were collected and sent to Ciaran (AU) as agreed in December
      • Preparation of github structure for tasks and subtask ongoing
      • No news from gas providers
      • I believe how strongly to tight the screws on PMMA was tested
    • 09:05 → 09:06
      Stefano report 1m
      Speaker: Stefano Piacentini (GSSI and INFN LNGS)
      • WP5 weekly meeting will be scheduled on Tuesdays at 14.30 (in the weeks of the general meeting)
      • Kickoff meeting relevant outcome:
        • investigation on the krypton source purchase feasibility
        • Herman will build a single module for both sides of CYGNO-04
      • We are uploading the latest data collected by LIME on cloud (connection of the daq LIME server to the network and update of the software tools done)
      • Nothing else to report
    • 09:06 → 09:07
      Giulia report 1m
      Speaker: Giulia D'Imperio (Istituto Nazionale di Fisica Nucleare)
      • Giulia working on CYGNO-04 simulations. GEM (Geant4) finished. Some inconsistency found between HPGe and ICP-MS radioactivity measurements.
      • Ongoing discussion with Davide F. to update the CAD version in Geant4
      • Request from Giorgio of some simulations for fiducialization studies
      • Simulation meeting today at 2
