LHC closed??

Hey, i heard that some hydrogen pipes in the large hadron collider broke and caused leaking of the gas... so now the experiment is at a halt... is this true??

if yes, then when will it start again?
some people said that it will take 2 months!

I was really excited about the LHc experiment, even though i dont know much (i'm in d 9th grade!), but now it has stopped...

arrr Evil or Very Mad

pls reply!

The LHC suffered a major loss of helium coolant. This means that, once the leak is repaired, they will need to cool the magnets down again. That will take several weeks and I think your estimate of 2 months is fairly accurate.

To be fair it was almost inevitable that there would be some problems - the LHC is cutting edge (some would call it 'bleeding edge' technology) and many of the components are completely new - so making it all work is a major enterprise in itself. The LHC was never going to produce the really exciting stuff immediately in any case - it looks like we will just have to wait a couple of months extra.

Oh shucks we all get a few more months to live. Just kidding I think all the people that think it's going to cause a black hole are crazy. But I think it's a waste of time, energy, and money none the less.

The probability that something wouldn't go wrong was so low that it was almost inevitable that something like this would happen. I wouldn't be surprised if something else didn't go wrong after this, and probably several times after that as well. The machinery that they are working with is so large and so complex and at the very edge of our capabilities that something is bound to go wrong.

I mean, you think how many times your PC at home goes wrong; the technology they are working with is a million times more complex, so you've gotta expect at least a couple of things to go wrong Very Happy

yaa i agree

I really share the same feeling. It was thrillingly great to hear such kind of machine was made back 1 year ago. Still remember I was wondering whats going on after the reported first run but without any further story about the outcomings followed nearly for several days until the sad news on the glitch. I understand it happens anyway when such complicated stuff is put together to work as one piece. Modern scientist are really winning lottery not by chance but by precise calculation. Heard it would run again in Dec this year. Wish some good results will turn out. Science prevails.

Article in the newspaper today says that the LHC will be shutdown until spring because of a failure in one of the magnets.

This is a really big setback for the experiment. The helium coolant failure looked set to postpone the experiment for roughly 2 months, but next spring is long wait for everyone eager to see what results the LHC will bring.

The LHC might make a black hole, we may just never get to a point where we can see if it is true. Very Happy

What sticks out for me was the remark by one of the engineers saying that some of the technology in use in the apparatus was not part of the original design when work started over 16 years ago but has been included now because of obvious benefits,
However these subsystems have been placed inside the whole system and this kind of "after thought" engineering may well cause these problems (Temporary closure because of unanticipated stress within the structure).
Why did they not anticipate the leak of the fluid? Was the testing incomplete? This might be a result of redesign at short notice as the testing cycles become more complex.

I suppose we are to expect delays with an amazing undertaking such as this. I just hope that none of the errors result in something dangerous. Not that I think the black hole scenario is likely, I'm thinking more European local issues.
