CM09 arrived in UU. Shock loggers data show smooth travel, just some spikes during unloading, SRF incoming inspection done.
Cernox 'issue': the T values do not agree with P values (in some modules discrepancies of more than 1 K).
Calibration curves are given by IJCLab and directly loaded in FREIA (using IOC), without using any calibration curve.
Spacing between points in calibration tables s is 0.1 K => reliable data, the problem of discrepancy is likely to be in the assembly process (bad contact?)
Calibration of cernox sensors R=>T is done in IJCLab in two different ranges (1) 300K→10K and (2) 10K→2K
CM10: CCC starts today (Oct 27th)/ Cold tuning system test tomorrow. Cavities have been tested at parking frequency (not tuned to resonance)
CM12-Leak test at ESS:
Pressurization to 1.5 b in tank: no leak
Pressurization of coupler line to 3 b: no lkeak
Further analysis needed, but no leak found until now
CM13 delivery to UU is delayed, since electronic card for coupler chiller (needed during warm coupler conditioning before assembly) will not be at IJCLab before december:
potential mitigation is to test CM12 (only cool down and warm-up, no RF test) to double check no leak is present in double wall tube.
Nuno and Cecilia in UU from Tuesday morning to Wednesday to join dynamic HL measurements.
There are minutes attached to this event.
Show them.
