The GIF is going to be switched off next week so we will stop our measurements and put the chambers in air.
Luca presented a review of the data taken from the end of 2019 on ECOGAS mix 2. They confirm the trends shown also in the Amruta presentation, and probably more time will be needed to confirm if this ECO mixture could be good or not. We will digest the results during the Christmas holidays and then we will decide the mixture for the start of 2021.
Barbara proposed to plan if possible new HF measurements to compare the results with those already available on r134a and ECOMix 1.
Beatrice pointed out that January and February will be periods very busy for CERN group and with reduced man power. It is necessary to add people to be trained on this kind of measurements. Luca already did these measurements and has to be checked if He will be able to stay at cern during the first months of 2021. Beatrice will check the status of the equipment needed for these tests. We will check if also other people already available at CERN could be involved.
Gianluca proposed to organize shifts of one week per person in order to check the operations of the system, Gianluca will prepare a set of points to be checked. Every group will find one or two people to involve in these routine shifts. A google file to fill the shift will be prepared for the start of 2021.
Giorgia presented the results on ECOGAS mix2 in ROME2 lab. The mix is confirmed to be interesting. The proposal is to check between all the labs that already did tests on this mixture (LNF CMS, ATLAS RM2, CERN, BARI) the wp defining clearly for each group the standard Temperature and pressure used as reference and the threshold used.
Davide will prepare a table to be filled.
Discussion on the correction on the WP due to the drop of voltage around the electrodes during irradiation that could be not negligible,
