    • 09:01 → 09:02
      DavideP report 1m
      Speaker: Davide Pinci (Istituto Nazionale di Fisica Nucleare)
      • Status of Cesidio corrections (complete or not): main part of corrections was done. Some details still to be fixed and cross-checked by Filippo Rosatelli currently at home on sick leave;
      •  Antonio’s delivery timeline: depends on the next corrections
      • Amazon purchases: 
        • O-ring already at LNF (provided by Bussetti)
        • screws purchase order submitted to Amazon on Jan 22nd
      • PMMA:
        • HV flanges need to be sent back to Bussetti to be thinned by 4 mm;
        • source flange need to be sent back to Bussetti to be machined to realise the groove for the O-ring. Cesidio already prepared design for this;
        • both shippings in pause awaiting a reversal of the correct accounts at LNF
      • Gas System:
        • foreseen for today tightness test
    • 09:02 → 09:03
      Elisabetta report 1m
      Speaker: Elisabetta Baracchini (Istituto Nazionale di Fisica Nucleare)
      • Elmer simulation for saturation and focusing (NID) test
    • 09:03 → 09:04
      DavideF report 1m
      Speaker: Davide Fiorina (GSSI & INFN)

      Hardware & Assembly
      - HV O-rings and screws for the GEM assembly are now available.
      - LNF box assembly is currently stopped due to a missing O-ring seat; the component has been sent back to Bussetti.
      - LNF field cage dry-run assembly is also on hold because the Nylon 66 guides were out of tolerance. Re-machining by Tecno Alarm is scheduled for this week.
      - Order for Nylon 66 fittings has been completed, delivery 29/01 at LNGS

      Mechanical Design & Drawings
      - Copper drawing will be delayed by ~2 weeks due to the temporary unavailability of Filippo (Antonio’s supervisor).
      - Polyethylene drawing is largely complete and nearly ready for LNGS services review, only final cleaning is needed to make it usable. In parallel, discussions are ongoing with Andrea Ianni to define the customs (dogana) procedure.

      Transport
      - LNF transport was successfully completed.
      - Two additional trips are planned to remove all remaining LIME water tanks from LNF.

      Papers
      - HFO paper is finished and awaiting feedback from Florian.
      - First internal review of the Directionality paper is ongoing between me and Samuele.

      Procurement & Administration
      - Affidamento with Rometec is progressing at GSSI.
      - Initial discussions started with NIER for the PRA update related to the Liquid Nitrogen (LN) system.

      Other
      - Clarify whether the EHD lens can be measured with HPGe.

      Andrea report 1m
      Speaker: Andrea Messina (Istituto Nazionale di Fisica Nucleare)

      • renewal of the mandate or replacement of PubComm members whose term is expiring

          • --> RENEWED from JAN 2026 for 2 years 

      • request to local coordinators to check the authors in their groups and report current activity and percentage of commitment

          • DONE

      • authorship rules

          • DONE, added few lines in the twiki: "Each INFN author must be present in the INFN books as a member of CYGNO or INITIUM. Undergraduate students may sign papers that include results from their thesis work. Temporary collaborators, such as theoreticians, may sign papers to which they have directly contributed."
          •  

      • authorship rules during the transition from LIME to CYGNO_04

       

      Our proposal is that authorship for CYGNO does not automatically translate into authorship for CYGNO_04. We believe it should be the responsibility of the local coordinator to evaluate who the active authors in their group are and to fill in the authorship table, indicating in particular the start and end dates and the activities the person is carrying out within CYGNO_04 to qualify as an author.

      The working package leaders will then review these activities and, if needed, discuss with the local coordinator the actual level of commitment of the person involved.

      We do not think it is appropriate to define strict or rigid rules to identify authors or to remove them. If specific cases arise that require discussion, this should first take place between the local coordinator and the relevant working package leader(s) possibly involving pubcomm.

      To make this explicit, we propose to add the following bullet to the CYGNO_04 authorship rules:

      • Authorship for CYGNO_04 is based on active contribution to the project: only collaborators who contribute to CYGNO_04 activities should be included as authors. The identification of active authors is the responsibility of the local coordinator, based on declared contributions to CYGNO_04 and validated by the relevant working package leader(s).

      We will take a few days to evaluate this proposal, possibly amend it, and then add it to the Twiki.
