LHC Repair Update: Temperature Must Be Raised so Repairmen Don't Die
Posted by Gizmodo US Edition at 6:00 AM on September 21, 2008
In case you were still worried about the LHC bringing on the biblical apocalypse, you can calm down, because it turns out the Collider is going to be out of commission for a lot longer than previously thought. The "electrical transformer" problem wasn't the cause of the shutdown at all, and the real problem means the LHC won't be back up and running for at least two months.
CERN spokesman James Gillies explained, ""It's too early to say precisely what happened, but it seems to be a faulty electrical connection between two magnets that stopped superconducting, melted and led to a mechanical failure and let the helium out." The specific section will have to have its temperature raised significantly above its usual absolute zero so engineers can go in and repair it without dying, which is apparently a very time-consuming process. This kind of failure isn't unusual for particle accelerators, but the LHC's internal temperature makes the whole ordeal much more difficult. Each warm-up or cool-down takes a minimum of several weeks, so the total repair will last more than two months. I suppose we've waited a long time already to unlock the secrets of the universe, so a couple more months can't hurt, right? [CNN]

The temperature inside the LHC can't be absolute zero as no one has been able to achieve such a low temperature. They have managed to get it to just above, something like 1 millionth of a degree above 0 Kelvin but not all the way there.

I was so looking forward to this. All the hype and build up and then this! Nothing! Hum bug!

Maybe its a sign that they shouldnt do it.

It's impossible to reach absolute zero, the temperature at which all molecular motion stops. The LHC's superconducting electromagnets operate close - cooled by liquid helium, they reach 1.9K, or -271.1C. Make no mistake, it's cold.
I love you, Giz, but this info is easy wikipedia junk.

A watchdog group had a debriefing about the problem the other day, ..."It's a small thermal exhaust port, right below the main port. The shaft leads directly to the reactor system."....

So what if it's 2 degrees above absolute 0 Kelvin, just layer your clothing.

Thanks faulty cooling! You just gave humanity an extra few months of existence.

They most likely mean near absolute zero since true absolute zero has not yet been reached. Even the failures with the LHC sound awesome though.

I'll donate my old CPU fan if that helps any. That sucker kept my cpu near absolute zero, well around 50 degrees above that but still closer than the surface of the sun or the AMD cpu chip.

@PocketLint: ehhh um either you are unaware of what absolute zero is or you have one hell of a cpu cooling fan. Absolute zero is -273 degrees C and I doubt your cpu cooling fan gets ur processor to -223 degrees C.

Why no robots to do the repairs? Materials may have different properties near absolute zero, but surely there are alternatives that would work just as well.

@Xenocide: According to the Science show MST3K, if you hit absolute zero, all molecular motion ceases and causes a chain reaction which will destroy the world. Luckily Crow shattered before Tom got him down to Absolute zero.

So the LHC staff gets to take vacation early this year except for the QA team, who get to donn their arctic suits to check up on the hardware.

Absolute zero would mean that we've moved past liquid helium and on to solid helium. In fact, solid anything whatsoever.

@PocketLint: I think he is talking about what they measure CPU temp in, Celsius. Where his CPU idled at 50 C, which is far from ABSOLUTE ZERO. zero celsius is 273.15 kelvin where as zero kelvin or absolute zero is -273.15 degrees Celsius

I'm amazed they can get so close to absolute zero. Imagine how cold that is and what kind of insulation is necessary to stop virtually all heat energy from entering the system.

If the LHC team needs help keeping the temperature low around there, they should use my ex-ex-girlfriend. Her name is K*r*t* F*o*d. She is from Scotland, she is covered in homemade tattoos, and damn she turned out cold.

@ p.fortin: ditto.
I for one would not be at all surprised if this thing doesn't get really humming till 2012.....seems like so many important things have already been planned for 2012....damn, hope the Mayans know what they stirred up.
