      Previous week recap (by person) — week of this meeting

      Davide P.

      • Confirmed trigger module commissioning readiness: Herman planned to assemble 50 Ω termination resistors this week.
      • Completed vessel validation tests: source flange + new O-ring, and 1/8" gas connectors up to +3 mbar.
      • Reported 3DExperience permission issues still impacting copper-box drawings closure.

      Davide F.

      • Humidity sensor procurement blocked by supplier incompatibility with Public Administration; alternative supplier search started.
      • O₂ sensor procurement still waiting for quote and required documents.
      • Copper-box drawings: 3DS issue solved; Antonio expected to provide final drawings this week.
      • Inner GEM frames retrofitted by Tecnoalarm; assembly test scheduled for tomorrow.
      • Rometec: first batch order submitted and under follow-up.
      • Hall F: inspection with technicians and LNGS services to finalize routing paths.
      • Water tanks transported to LNF; receipt/inspection pending.
      • Defined LN2 line requirement: continuous copper line (avoid SS + Swagelok approach).

      Giorgio report
      Speaker: Giorgio Dho (Istituto Nazionale di Fisica Nucleare)
      • No real news from analysis.
      • Littleupdates from Igor on digitization and check with analysis.
      •  Today meeting with Edward Shields (Australian) and Federico (who won 3 months grant thanks to GSSI) to possibly improve  diffususion deconvolution
      • Premounting of GEMs looks ok with the bent bandelle. We will see when we try to mount
      • Field cage foils do not have the holes to secure it in position. Tomorrow we will try to understand how to deal with this
      • GEMs were repaired and are ready. Waiting for Luigi to understand how to bring them back

      • No reply from both contact persons for the Rb-83 source
      • Last week: DAQ meeting. Discussion about gas tightness tests results using N2 -> foreseen operation conditions 3+-2 mbar overpressure
      • New DAQ tested on a long data-taking in MANGO. Apparently everything ok so far.
