Slowly the LHC is restarting.

I always wondered if anyone else watched the test runs.
AND all the different pages you can look at there to see what is happening.
Also all the things you can look up.

Beam setup :injection probe beam ( setup beam) right now

I notice the "stable beams" announced in some twitter accounts.

From official Cern Twitter account:
"Today we're planning LHC test collisions at 6.8 TeV - the highest ever energy in the history of the accelerator!
These tests are an important milestone in the preparation for #LHCRun3 in July."

From CERN Twitter Official Account:

Join CERN scientists live on 5 July, 16.00 CEST to celebrate the first collisions with stable beams at the world-record energy of 13.6 TeV, a milestone that will mark the beginning of the third physics run of the LHC

The LHC has restarted, but every few days it's stopped for repairing, scrubbing, cooling, rather than running.
There is no physics beam in LHC for over a day. I hope the problems do not recur again and again, there be protons colliding at 13.6Tev nonstop.

Bad news:
RF will be warmed up to room temperature following the cooling tower fault in point 4.
No beam for the next ~4 weeks

A bit OT, but I have been wondering whether all the energy problems in Europe will affect LHC.
They should have access to nuclear power from France and hydro from Switzerland, but if things get tough, even they may be hard to come by.

It is not something that you usually have to worry about, but these are not exactly usual times.

The LHC RF system tripped frequently to the point that klystron is replaced for a new one.

Hopefully with this opportunity the LHC engineers can repair the RF system.

Meanwhile the LHC magnets remain at 2K, allowing more time to train the magnets.

The LHC run 3 performance is excellent, but the LHC is stopped for repairs too many times.
If the LHC is still that unreliable, I can't imagine what the feeling would be that the 100km FCC sits idle almost all the time waiting for things to be repaired here and there!

A large part of FCC instrumentations still don't exist.
So, maintenance will be a nightmare.

What does that involve?
