Participants: Alessio, Alex, Bianca, Giorgio, Grzegorz, Iza, Livio, Krzysztof, Maxim, Oscar, Roberto, Susana, Tomasz, Vicente. MC Simulation and R.A. budget updates: Maxim: SaG4n rolling. Comparison TENDL vs JENDEL looks good. Discrepancy NeuCBOT - SaG4n too big. Step size to be tuned or wrong biasing New discussion with Vicente Pending. No progress on the note Vicente: Need to evaluate the latest results (Gd and conenctors). Cosmogenics: New Ar activation studies presented. Possible meeting with Andrea et al. about Ar transportation to tune the details about transportation (not urgent). Results: 0.022 mBq/kg (negligible compared to 0.73 mBq/kg). Important safety margin. Meeting with DEAP collegaues a bout muons UG (higher priority) Surface contamination: SS sheet ready to be shipped to Legnaro (Cu sheet already at Legnaro) Meeting with the TPC working group needed to calirfy the SS parts size and welding still to be organized. SS-Electropolishing probably too expensive. It is necessary to investigate whether there a re commercial companies able to do that. VETO cleaning protocol: Can we conclude whether we need it? Assays status: Iza: connectors for the steering module reported Ultem 1000 (two weeks measurements): report in the DB Sami siltem from Saverio to LNGS (5 kg) still not delivered Susana: Gd results from LSC. Confirmed the ICPMS results from MSU. Factor 2 worse than Russian purest one, no Po-210 measurement in any case) Tomasz: Inductors preliminary: 6 Bq/kg. FEP not doable now.
