Second Snag This Week Could Delay LHC for Weeks 160
sciencehabit writes "After a transformer failure earlier this week, the Large Hadron Collider has hit another snag — and this one is much more serious. As Science reports, 'At least one of the LHC's more than 1700 superconducting magnets failed, springing a leak and spewing helium gas into the subterranean tunnel that houses the collider ... How long [repairs take] will depend in part on how much of the LHC must be warmed to room temperature for servicing. If it's only a short section, the repair could be relatively quick. But the machine is built in octants, and if workers have to heat and cool an entire octant, then the cooling alone would take several weeks."
Reader Simmeh contributes coverage from the BBC. We recently discussed the transformer malfunction at the LHC, which was a smaller problem and has already been fixed. Update - 9/20 at 12:52 by SS: CNN reports that the LHC will be out of commission for two months.

I would have been amazed if a structure as complex as this worked the first time the switch was thrown. Think about how simply enormous the LHC [wired.com] is. It has miles of wire, gigantic magnets that have to be perfectly synced and placed with amazing accuracy. It's not like LHCs are turned out every week. Gigantic super colliders are HARD to build.
They'll eventually iron out all the problems and can proceed to cause the world to end.

And even if it does turn out to be completely useless for physics, I would have much rather have seen my US tax dollars be wasted on something like a particle collider than how they've been wasted in Iraq. Money spent on science is almost never truly wasted.

actually that might be worse; if all magnets must be online to keep the beam stable, having many magnets just make the statistical incidence of failure higher...

"It cost 70 bazillions of dollars to build, and now it's BROKE? What, they never actually DID anything with it yet either? What a joke" they'll say.
From the perspective of the non-geeks, this thing is a perpetual money sink, a haven for nerds to tinker and fiddle with things that require unending tinkering and fiddling by design, with only a carrot of some potentially really great stuff that just might some day dribble out of the thing.
Think about it, whoever wrote the grants or whatever that got them all that money is a genius - "Ummm yes, I need 70 bazillion dollars. What does it do? Ummmmm, yes, it will have the potential to reveal to us the HIGGS BOSON! Yes. HIGGS BOSON. What good is the HIGGS BOSON? Ummmm, yes, the HIGGS BOSON promises to reveal to us the very SECRETS OF THE UNIVERSE!
Go LHC! As a geek myself, I say we need more of these things!
