• UU will cool down CM12 again for leak tests at cold in January 2023
  • Artur's group will bring the oil-sealed leak detector and will join the experiment
  • Preliminary procedure: staying at 4 K for some days to accumulate He, thermal cycle up to 20 K, and then go down to 2 K and do the same thing
  • IJCLab will not join
  • If the leak in CM12 is confirmed, CM10 must be checked as well
• Rocio will bring shock loggers with her to use them for CM09's transport
• CM13 is blocked by a broken chiller of klystron + coupler conditioning bench
  • The system is being fixed and assembly will be restarted in  W49
  • The cavities (24&25) are ready and waiting in the clean room
• CM14 requires the new set of double-wall tubes and they are still under farication
• Nicolas reported that the stepper motor was again stuck at cold after fixing the "axial play issue"
  • Good news that the issue was not from the axial play
  • The newly designed adapter is mounted and was ok at warm and is being cooled down
• ESS-IJCLab governing meeting will be held in two weeks time where all the issues will be discussed
