LHC helium leak will shut collider down for two months

More glitches for the Large Hadron Collider (LHC): The same day operators announced that a 30-ton transformer that cools part of the particle smasher had broken within hours of the LHC's launch last week, a mishap yesterday resulted in "a large helium leak" into the collider's tunnel.

According to a press statement, "the most likely cause of the problem was a faulty electrical connection between two magnets, which probably melted at high current leading to mechanical failure."

No workers were at risk, according to CERN, the European Organization for Nuclear Research, which runs the LHC.

The leak means that the LHC will be down for at least two months, because workers must now warm up the faulty sector of the tunnel in order to repair it. The liquid helium is used to cool the LHC's magnets -- which guide protons and accelerate them so they can be smashed together -- down to within 1.9 kelvins (3.4 degrees Fahrenheit) of absolute zero.

For more on the LHC, see our in-depth report. It may be even longer now before we find out how long it takes the LHC to defrost a pizza.

    I wonder how many claims of "answered prayers" we will have to deal with now about this........

    I am sorry to have to say this, but 1.9Kelvins is not 3.4F - its around -456.25F or -271C.

    I apologize, I see it says 3.4F of absolute zero. A little confusing while reading the first time through.

    it actually says 1.9 kelvins (or 3.4F) of absolute zero. since kelvins are "degrees above absolute zero" (for some value of "degrees"), it's clear you were misled by the misplacing of the closing parenthesis, which should have come after "zero".

    or something.

    So what happened to the high-Tc superconductor hype?

    Why are you Americans still using Lbs, Miles and Fahrenheit? How about showing a little broad mindedness and use terms that the rest of the world uses like kilograms, meters and degree's celsius. Time to wake up and realise that there is another world out there.

    lol, if we did that, then the people we live with, not to mention our teachers from k-12, would not understand a thing we were talking about!

    I know! I dislike the fact that we Americans still use miles, Fahrenheit, etc... high schools are the problem, not so much higher education and academia -- they've actually adapted for the most part.

    To all readers, please have a little courtesy when using the term "American." I'm an American, but I'm not from the United States. I'm an American from Canada where we do use the metric system, and we do speak and write proper english, Yes, I know the definition of American has changed over time, but the change was the result of a taking by the United States and not a process where non-U.S. Americans aggreed to give redefine the definition.

    Please be aware, there is a growing concern among Americans, not from the United States, that we are being associated with those folks from the United States, and quite frankly we want nothing to do with the United States.

    If I may make a suggestion; do what we do here. Simply refer to those folks down-below as "Yanks," or the longer version, "those arrogant, self serving pieces of ..."

    If you happen to be making a reference to Americans in the continent of North and South America, then feel free to use the term Americans.

    Thanks!

    Will this instrument answer the ever lasting questions of how to cure disease, or how to solve the water shortage problem or white out starvation across the world, how about restoring natural resources, like oxigen. If it cannot or will not...WHY is it important? Put the real money to real use! There are great growing minds out there like our future population KIDS.

    Will this thingamajig find answers to the everlasting questions like, cure diseases, end starvation across the world, restore natural resources like oxygen, avoid natural catastrophic disasters, protect the planet in a bubble. If it cannot and will not answers these, then DO THE MATH---put the real money to real use and help evolve the evergrowing minds of our future Einsteins. They may hold the key to many of our own nomadic lifestyles. (Use everything we can from this land and move to another country once they are depleted or worthless)...??? THINK MAN!

    It has become appearant to me that black holes - ie absolute matter generating absolute gravity is in all probability the logical conclusion to evolution of intelligent life .

    by the way, here in America we often ask ourselves why we're not using metric. few of us think its better to use our "American" system of measurement. it has long been discussed switching and most product labels include both American and metric.
