Re: Quench 1pm 4 Dec 2009

I guess they just found the tolerance limit of part of the LHC then !

Re: Quench 1pm 4 Dec 2009

Page 1 now says "Start the recovery from access to the machine" so hopefully it's all OK.

Hopefully this was one of Chris's 'Quenchinos" :)

Quench 1pm 4 Dec 2009

LHC is reporting a quench in sector 23. Machine is stopped for access.

Anyone got any further info ? Nothing looksd amiss on the cryo etc so hopefully minor.

Re: Mental illness

Wow, a lot of posts in a short time. Well I'll just have a little ramble of my own. :D What is 'mental illness' for a start ? It's certainly not a binary thing. Certainly there are people who are obviously mentally ill, and people who obviously aren't, but in between there is a great swathe of grey ...

Re: Several biggest errors of particle physicists.

You need independent verification. Someone independent needs to verify your work. Validate your research. Check your results... You will have -zero- respect until you have someone check it. I wrote hundreds of personal letters to scientists. But I did not received any reasonable answer from them, e...

Re: Several biggest errors of particle physicists.

I give the following probabilities: A. 10% - magnetic collapse will start at 0.45 TeV; B. 50% - magnetic collapse will start at 3.5 TeV, if A did not happen; C. 70% - magnetic collapse will start at 7 TeV, if B did not happen. 30% I leave to my mistake. 10% chance over what period ? Given that the ...

Some form of Quantum Zen theory then ? If a collider bashes particles together, but no one is there to hear it does it make a noise ?

Re: *** MAJOR power loss and many systems down

I love this entry in hte LHCb Logbook from the time of the power loss. Someone's keen for a break it seems !

18 kV drop on the Meyrin site....
6 LHC sectors tripped.
I guess this will give some rest.

Re: What sort of noise does the worlds largest machine make?

Surely the collisions can't make any sound since they occur in a vacuum ?

Re: *** Breaking news ***

They've had ALICE and ATLAS powered up most of the afternoon, but I've not seen any signs of them ramping up the beam power at all.

I've got two screens on my PC at work. The secondary one is normally dedicated to server monitoring, it's currently dedicated to LHC monitoring ! :D
