Norihiro presents slides on a possible new magnet for Amber, starting with a physics explanation.
This is a call for interest for a preliminary study to be performed in view of an upgrade that needs to undergo the proposal/approval stages. Help would be needed to make a preliminary feasibility study for a dipole magnet, 130 cm long, 40 x 40 width/height. Uniformity is paramount.
Moritiz presents slides on the a required mapping for SM1 SM2.
August 2026 is currently the date of preference for the mapping to start.
Round table;
Matthias: ATLAS magnet operation was smooth. Still some time to go until December. There was some work on Alice for the new magnet. IAXO collaboration is next week.
Christoph asks if there are results from the Wuxi-Toli manufactured Al-SC. It was qualified by the university of Twente. The results were good seemingly. For Baby IAXO cold working is needed.
Anna reports on the good quality of the interface between SC and Al. The conductor is relatively small. They did at least 1km of continuous length. Tratos is work in progress, as the machine is shared between productions. Next trial will be done middle of September.
Macej. CMS is off. Was stopped on Monday because of cryo problems (filter regeneration). There might have been some humidity injected during YETS. Ramp up is pending.
Moritz: There was a problem with SM1. There was a couple trips. Looks like an issue with the water flow. There was probably an issue with the temperature threshold. The problem should be looked into also by DT.
Xavier: Alice and LHCb magnets are stable. There is a problem in the PC of the Alice solenoid. The magnet was off for one week. Colleagues from EPC fixed it.
Lukas: Successfully published the paper about the new hall card. Raphael is making a new calibration bench for calibrating the probes up to 2.5 T. New encoders are being implemented to improve rotational accuracy. A temperature control system was developed. During YETS we will be mapping the gap behind ECAL.
Jarl: MNP 17 was run for 8 hours over 2 days at 1T.
