Present:

Matthias Mentink, Anna Kario, Lukas Messner, Xavier Pons, Sylvain Ravat, Jarl, Tony, Heinrich, Macej, Burkhard, Nicola, Benoit, Maarten (remote), Pascal, Jakub Mihal Polak

Matthias gives the presentation given recently during the FCC-ee meeting.

Burkhard: we should keep thinking about Alice upgrade. At the moment Alice is advancing quite steadfast with Brazil.

Benoit: the process in italy (Tratos) is advancing. There were some issues with the pressure. MK technology in Japan is a new player, with significant knowledge, and is entering the discussions, though there are some points to be clarified about confidentiality. This research is of interest for BabyIAXO and potentially for Alice 3

 

Round table

Matthais: ATLAS Magnets are running well.

Anna: -

Lukas: -

Xavier: Finished the YETS activities, entering operations. The magnets are operating well. We had a minor issue in Alice power converters with the dipole. A power resistor used for feedback regulations burned. It was replaced and it works fine. The solenoid went through a power glitch but it ramped up again correctly. Activities for TS, YETS and LS3 are being prepared. For the TS there is a particular task in LHCb: bypass the issue with the water cooling temperature. There is a thermal switch and PT1000 on each pancake, but after mounting the experiment the sensors are not accessible anymore. The MSS should act on 2 thermal switches, not only one.

Sylvain - like Xavier

Macej: - The magnetic switches are special for magnetic field and they have a special property that they stay open once they open. 

Jarl: MNP17 can reach now 1T @ 40 something degrees. MNP24 seems to overheat past 1T. EN-CV had a survery of the cooling plant. The upgrade continues slowly

Benoit: CMS magnet is working fine, cryo is stable so there will be no regeneration unless some works will take place. M1 the cooldown has started and there will be a run next month for CMS Tracker and HGCAL. Still looking for a budget for the consoldation of a valve on the magnet. 150 k asked for by the Cryo team, but since everything is working not much is happening. The only possibility for intervention is next YETS.

Maarten: The proposal for NA60+ is approaching completion.
