Re: 2022 Operation
Yeah we're commissioning a brand new detector (without a hardware trigger) at LHCb. I guess the new lumi monitor (PLUME) isn't ready yet.
First 6.8 TeV stable beams currently scheduled for 5th July (along with a media event, I believe?).

Re: 2022 Operation
I used to have access to these, but it seems to be blocked. Is this a change of policy that "fans of LHC" can't look in the logbooks anymore? I had so much fun reading these... Are you in the egroup invited-OP-elogbook-users? Access might have been lost in the move to the new logbook system. Might ...

Re: 2022 Operation
Had a first attempt at a 6.5 TeV ramp with beam. Dump before reaching 3 TeV due to 2 circuit trips (arc tuning quadrupoles). Cryo lost in S12 after ramp-down (triplet quench). "Expect few hours of recovery."

Re: 2022 Operation
Beam operation should commence Friday 22nd and last 2 weeks, until 6th May. Then there will be a 1-week break, in which the second half of the LHCb VELO should be installed.

2022 Operation
The machine mode has changed from "Shutdown" to "Machine checkout", so I suppose it's time to create a thread for 2022 operation. The schedule is a bit up in the air given the cryo problem in the RF system. The commissioning spreadsheet suggests that first beams may come towards the end of next week.

Re: October 2021 Beam Tests + 2021/22 YETS
Problems with RF cryo. This may push back first beams by a week (TBC), but machine checkout will still go ahead starting Friday.

Re: October 2021 Beam Tests + 2021/22 YETS
All sectors cold, powering tests ongoing. After cavern closure (24th March) Sector 23 needs a new magnet training campaign: ~20 quenches, 2 weeks estimated, then ready for beam injection.
