Rolling Report

    • 09:00 → 09:01
      Previous week recap 1m
      Speaker: Davide Fiorina (GSSI & INFN)

      Davide P.

      • CSN2: second draft prepared to be released.
      • Coordinated Herman logistics (CERN shipment tranches; return option via Luigi).
      • Provided gas-flange diameter to Bussetti; machining of source/HV flanges scheduled (11–12 Feb).
      • Flagged optical windows mismatch (only 6 mm supplied) and started follow-up.
      • Advanced DarkSide PE logistics (customs documents found; customs/polishing steps unblocked).
      • RM1 approval obtained to host 1 ton of LIME copper.

      Davide F.

      • Unblocked PRA update process on GSSI side; next step to engage NIER for evaluation.
      • Started “affidamento a consumo” with Rometec; continued chasing urgent PMMA-box fitting (still no ETA).
      • Kicked off Hall F workshop actions (gas-system flanges + dewar wheels adapter).
      • Water pool/PE/copper box: first draft ready; initiated technical report + TDR update; Environmental Service meeting scheduled.
      • Managed detector integration issues: cathode frame investigation arranged; GEM critical issue identified (oxidized GEM lost, bent Nylon66 frames; workaround and CERN options under evaluation).

      Giorgio

      • No analysis update (meeting canceled).
      • Prepared to present the new analysis task-management tool at the general meeting.

      Stefano

      • Set up first 2026 WP5 meeting.
      • Investigated the possibility to borrow an Rb-83 source from XENON.
      • Follow-up pending on He bottle procurement for commissioning.

      Giulia

      • Resolved GEM radioactivity inconsistency (HPGe DB typo fixed).
      • CYGNO-04 simulations continued; CAD vs Geant4 geometry alignment still to be verified.
    • 09:01 → 09:02
      DavideP report 1m
      Speaker: Davide Pinci (Istituto Nazionale di Fisica Nucleare)

      - The second batch of Mouser components has been delivered to CERN and we have agreed with Benussi on transport to LNF;
      - The gas connectors have arrived at RomeTech, we have opted for shipment to LNF;
      - Material sent back by Bussetti to LNF, already arrived. 

    • 09:02 → 09:03
      Elisabetta report 1m
      Speaker: Elisabetta Baracchini (Istituto Nazionale di Fisica Nucleare)
      • Found a place to store LIME copper in LNGS GSSI Lab
      • Discussion ongoing to understand how to store them with GSSI colleagues
    • 09:03 → 09:04
      DavideF report 1m
      Speaker: Davide Fiorina (GSSI & INFN)

      • O₂ + humidity sensors: procurement phase started (quotes requested), budget ~15 k€.

      • Gas supply: procure He and CF₄ bottles at LNGS, using all remaining money from last year.

      • NIER and PRA started the collaboration to produce the new PRA, several documents and feedback are needed and will be provided to the company

      • Water pool / installation procedure: with Cesidio, fully reviewed installation procedure and water-pool integration. Met LNGS Environment Service: they support no additional resin layer, using only the existing resin + silicone sealant on the edges. Major simplification/relief.

      • CYGNO-04 workflow (current):

      • Complete handling procedure for polyethylene + copper box (our side) this week.
      • Discuss technical/crane aspects with LNGS crane contact (Franco Tacca); expect feedback/indications by end of week.
      • Budget contingency: possible ~10 k€ for cranes (likely not needed, but ready).

      • Close copper + polyethylene package and send everything to Fantini, priority: polyethylene.

      • Water tanks: first indication of availability; top cable entry space feasible. Cost estimate ~20 k€, depending on current polyethylene market value.

      • Simulation inputs: volumes + weights for all CYGNO-04 components are available; with Giulia define how to update the simulation accordingly.

      • HFO paper: helping Melba implement final comments from Florian.

      • Directionality: trimmed/cut some details.

    • 09:04 → 09:05
      Giorgio report 1m
      Speaker: Giorgio Dho (Istituto Nazionale di Fisica Nucleare)
      • Analysis github page for the task was presented
      • GEM packed and waiting for a document from magazzino to be sent
      • Luigi has not yet been able to meet Adam or alexis
      • Tecnoalarm has now the cathode frame and GEM sandwich to correct the bends
      • It is not working to straight things up. Tuesday we expect new updates.
      • Daniele will send where to cut the middle bandelle asap
      • Cesidio warned that Bussetti's stuff has arrived if he wanted to check the pieces. He did not reply to me
    • 09:05 → 09:06
      Stefano report 1m
      Speaker: Stefano Piacentini (GSSI and INFN LNGS)
      • Xenon will not lend us the Rb-83 source, but they shared with us the information for the procurement of the source
      • No other relevant updates to report
    • 09:06 → 09:07
      Giulia report 1m
      Speaker: Giulia D'Imperio (Istituto Nazionale di Fisica Nucleare)
      • Collected all available gamma measurements taken with NaI at LNGS and LNF on github: https://github.com/CYGNUS-RD/NaI-gamma-measurement
        At the moment the repository is private but can be made public.
      • Next simulation meeting is on Monday 23/02 at 2 pm
    • 09:07 → 09:08
