October 2021 Beam Tests + 2021/22 YETS
Re: October 2021 Beam Tests + 2021/22 YETS
It's nearly the end of YETS, and the cryo status board has just achieved a 'sea of green" - whoo hoo.
Re: October 2021 Beam Tests + 2021/22 YETS
Magnet powering tests seem to be visible on the Magnets status page:

Not sure if there is a better way to visualise magnet training exercise progress.

Problems with RF cryo. This may push back first beams by a week (TBC), but machine checkout will still go ahead starting Friday.

That's actually the experiment's magnets. They are also being tested and ramped up these days, but do not need to be "trained" like the LHC's superconducting circuits.
Best way to see the training progress is https://lhcpoweringtests.web.cern.ch/lhcpoweringtests/. You see all sectors are validated for OP except 23, which is close both for the dipoles (RB) and quadrupoles (RQ).
Also on the cryo page https://op-webtools.web.cern.ch/Vistar/ ... p?usr=LHC2 you see a peak in the temperature and the cryo flags going red for some 6-8 hours of recovery every time the dipoles quench.
For the quadrupoles the temperature increase is less visible but cryo flags will still be red for a while.

Yes its been quite interesting. The main vistars page has also shown some action recently.
