Melted wires knock out Hadron collider for two months


September 22, 2008
Just days after a faulty transformer was repaired, an apparent melted electrical connection between two magnets has brought the Large Hadron Collider down for two months.

Bolek Wyslouch, an MIT physics professor who is working on the project, said today that problems arising at this point in testing what is the world's most powerful and massive particle collider should not be unexpected. He declined to comment further on the latest problem.

Wyslouch, who has been working on the collider project for seven years, said the same thing last week after a 30-ton transformer failed on Sept. 11. That transformer is used to power coolants in the 17-mile underground, vacuum-sealed loop in the particle accelerator.

"So one thing didn't work. It's not a surprise," said Wyslouch last week. "There are many, many elements, and some of them had never been used and some of them break. You fix them and keep going. It's impossible not to have things break."

Then CERN -- as the European Organization for Nuclear Research is known -- reported that last Friday, the electrical connection between two magnets melted, causing a "large helium leak" into the tunnel. A CERN release said that "at no time was there any risk to people."

This latest problem comes just two weeks after the first test run of the collider, which Harvey Newman, a physics professor at the California Institute of Technology, called "one of the great engineering milestones of mankind." In that Sept. 10 test, a particle beam made the first full circuit around the tube. After that, another beam was shot around the tube going in the opposite direction.

These tests are a build-up to the time when two beams will be shot around the tube in opposite directions on a collision course. Smashing the beams together will create showers of new particles that should re-create conditions in the universe just moments after its conception, giving scientists the chance to answer one of humanity's oldest questions: How was the universe created?

Last week, before the melted-wire problem, the collision test was expected to take place in a matter of weeks. Now, it will be pushed back at least until the end of November.

Controversy has swirled around the collider and the experiments being done there. Rumors have been circulating around the Internet that the experiments might destroy the universe by accidentally creating a black hole that would suck everything and everyone into it.

Under the Big Bang theory, many scientists believe that more than 13 billion years ago, an amazingly dense object the size of a coin expanded into the universe that we know now -- with planets, stars, black holes and life. Some people fear that by smashing the particle beams together in the collider, a similar cataclysmic reaction might occur, vaporizing our planet or sucking it into a black hole that would shoot it out into an alternate universe.

Fears about the experiments reached such a furor that Frank Wilczek, an MIT physics professor and Nobel laureate, received death threats because of his involvement with the Large Hadron Collider.

Wilczek sat on the science advisory committee at the LHC for six years. He more recently took the government's side in a U.S.-based lawsuit filed by a retired nuclear safety officer and a Spanish science writer who called for more safety reviews to be done before any experiments are conducted at the collider.

I just read the article and about to post it but you beat me to it. ;D



Somehow I had a feeling a wire, capacitor, computer failure, or diagnostic tests would fail in the early stages.

i think all big projects have a tendency to fail at first try.

Its all very interesting, and alarmingly all very expensive. However, this bit doesnt make any sense. If they are re-creating conditions in the universe just moments after its conception, then surely that implies they belive this to be how the universe was formed. So why do they not know how the universe was formed?

What they are in fact doing, is trying to prove there own theories. They believe this is how the universe was formed, and so heres what it looks like in a multi billion dollar tube. great. ::)

For some big bang theroy to place planets and other things the exact distance required from other things such as the sun and the earth, surely is not possible. To many variables. But im sure there controlled conditions will show how it is indeed possible....

For it to then follow that we are incredibly advanced after evolving from fish and monkeys and what not, and are the exact correct size for our homeworld (think if we were 60ft tall! How big would cars have to be and houses???? conversely, what if we were 12 inches tall?) beggars belief.

Plus there are still monkeys and fish. Strange that. What the actual answer is i do not know, but spending a few more billion isnt going to prove it one way or another i dont think... ::)

Ill shut up now ;D

I don't know a lot about nuclear physics but I know History. Is it possible that the Hadron group are inadvertantly improving the the deadly force of military arsenals. I think I would rather know how the universe is doing now as compared to how it started. This topic is interesting. I'll check in to it now and again. :)

It's worth noting that this collider was not built simply for this one experiment- supercolliders are handy for figuring out and discovering all sorts of things.
I don't know about all the fuss over the risk of some sort of cataclysm  , but I do know that the eggheads behind the first A-bomb tests were taking bets on whether or not that would cause some sort of planet-wide atmospheric chain reaction... supposedly they were not all in agreement as to whether or not it would do so.

I hope this team remembers their history...  :o

But the little I know about this experiment indicates that there won't be quite enough mass involved to compromise the collider itself, let alone destroy the world. "Size of a coin" doesn't mean "mass of a coin"... this theoretical proto-thing that may have spawned the universe would have been pretty darn massive, as everything that is would have come from it.

It'd be impressive if they proved conclusively that this was indeed how it all began, but of course people like me sitting in the back would raise their hand and ask "but where did this object come from, and what caused it to expand?"  ;D

As impractical as it all seems, though, I am a big supporter of such research. In good science, there's no such thing as useless data... every important scientific law we take for granted now, in theory and practice, was built painstakingly out of small bits of data, and often discovered by accident while trying to prove something else.

As for the teething problems with this device: as a technician, I understand. It's a very very large, complicated system, and it's fairly new technology.

I highly doubt that this is whats going to kill us all...

That said, though I support the research, I'm a bit skeptical about the whole "dark matter" bit. It's pretty much like saying (in vastly simplified terms) I have a theorem that states 1+2=10, but in reality, 1+2=3, so there must be some dark number that makes 1+2=10... Logic says either my math is bad, or my theorem is bad.

Either way, this will probably show that either:
a) we know a hell of a lot more than we thought
or
b) we still don't know anything.

Who knows... maybe Newton's Laws are only an approximation and they appear to be correct when you look at a significant object, but are incorrect at the atomic scale.

Many believe Einstein put a dent in Newton's laws of motion. But then when you realize they are only theory to begin with........ ::)

No, it was the flux capacitor circuits that blew. What worries me is if this broke down at a crucial stage of these experiments. There's no telling what would happen. We could all end up in a parallel universe. :o

The only time we all went out together. ;D

We're already in a parallel universe, perpendicularly speaking...Image
