- CM13 is under the test in FREIA. As cavity strings taken from leaky CM09 test, the comparison of conditioning behavior and RGA data was done. Warm coupler conditioning took 102 hours, compared to about 30 hours for CM09 (1st test). Oxigen signal is completely different from previous warm coupler conditioning.
- CM13 is cooling down. FREIA had some minor issue with cryogenic facility, but it is possible to fit to previous schedule. Start of MP conditioning is plan for May, 9th.
- According to Paolo email before the meeting: During mechanical inspection in ESS in CM11 found that the He outlet pipe of the couple is in tilted position and the coupler flange in a bad condition (oxidation and/or erosion).
FREIA team checked the log book. FREIA team confirmed that the Helium pipe arrived tilted. However, have not seen any issues with Helium during operation.CM11 have been tested in FREIA from May to the end of August in 2022. Unusual things, beside infro in a report for ESS: It stayed in a bunker during summer holidays with a water cooling connected without the flow. Didn't found any photo of coupler flange after the test. Akira also didn't found any explanation after the digging in IJClab archive. - Cecilia will be in FREIA from May, 8th to May, 10th.
- Any new information about CM14, i.e. it is scheduled to be in FREIA in a middle of October.
