I was there when there was a (much bigger) quench during commissioning of the LHC [0][1]. It was also at the focusing quadrupole modules - maybe the same ones?

I could make a joke about how it's Fermilab's vengeance for not having their own accelerator, but that would be dishonest: these focusing modules are the most complex ones of the whole ring.

- notanote 3y agoThe 2008 quench happened at the other side of the ring. (Sector 3-4 then, sector 7-8 now.) The physics run was going very smoothly up to now [0]. Last year part of the machine (RF) had to be brought to room temperature as well, after a cooling tower fault, and there was no beam for four weeks. I get the impression that this will take longer, but I hope not by much.
