Helium leak causes set back to CERN and LHC

The Large Hadron Collider near Geneva will be out of action for at least two months, the European Organization for Nuclear Research (Cern) says. This is a major set back for CERN and the LHC@home BOINC project.

LHC@home is a computer simulation of particle orbits and does not use inputs from the LHC, so it is going on.

Yes, I'm crunching a 1,000,000 turns LHC WU right now. The LHC@Home project is independent of the real LHC.

LHC re-start scheduled for 2009...

Apparently, the helium leak has destroyed two supercooled electromagnets and an entire section, and the time necessary for the investigation and repairs precludes a restart before CERN’s obligatory winter maintenance period, bringing the date for restart of the accelerator complex to early spring 2009. LHC beams will then follow.

A bad news...

Where did you see that news story?

I read in the newspaper today that the Hadron Collider will be down until spring 2009. I didn't know that the whole mileslong chamber had to be kept close to absolute zero. Maybe it'll take a long time to cool it back after repairs are made.

The whole chamber doesn't, just the electro magnets.

Reading between the lines it sounds like an electric short and small explosion which sent something into a liquid helium line and ripped a hole in it. Won't have a cause until it is warm enough to inspect and repair.

They will be patched in a couple of months, but they had to agree not to run it in the winter because the electricity it uses is needed for home heating in the winter.

One would assume Cern knows what their doing. I think the shut down was due to public outcry of what might happen. A little boy somewhere in the world (sorry don't remember where) killed himself thinking a black hole would stop the world and suck it all in. Maybe a town or city might be put out of place. All that being said, they will not find the "God" particle, or the beginning of the Big Bang. I'm working on the "Universe" season two, and it has left me to believe there is still so much we do not know.

But let me tell you this. I have proof these scientists may be several wires short of a working plug. jmo

Odds are that they will indeed find the Higgs Boson--It may take years of sifting through their data but a consensus will be reached--I betcha-- that they have found the Higgs. I would have thought that Fermi-lab would have announced also by now. An unfortunate nick name --"the God Particle" for the Higgs Boson.

As for the Big Bang--The claim is that they will achieve --albeit for the shortest instant--temperatures that have not been created since the initial singularity. They will not be replicating the Big Bang in it's full concentration of Energy. A few trillion electron volts just won't be any problem at all for the current creation we call the world.

Symmetry --like many math formalisms --seems to describe the reality of the world. Looking for the Higgs Boson is an effort to see if--in this case--Mathematics also describes reality or whether it is just math. For sure there are still things that we don't fully understand but knowledge will march forward --do we fully understand the structure of the atom or an electron ? Or do we have a good handle on Quantum effects ? probably not yet we can make predictions and use the science to our advantage and partial understanding.

Every time a star goes nova I am sure that the particle collisions are more energetic that what the LHC can generate. As these nova's don't get swallowed up by the "micro black holes" at higher energy than the LHC will use, I tend to put anyone who talks of such into the crackpot class.

Too bad for the kid that there are crackpots in the world who are so self centered that they spout their untruths to massage their ego and fatten their wallet, but ever has it been thus. The true shame is that the media puts them front and center knowing full well they are liars just so it can sell more advertising.

As to what they will find or not find, time will tell. I am sure however they can run numbers and know that they should reach energy levels (temperature) of the very early universe. They wouldn't have built it if they weren't confident of that.

We get collisions of that energy and much higher right here on earth, too. There are cosmic rays that hit the earth at energies as high as 3E+20 EV (search for "oh my god particle"), which is several thousand times as high as the LHC's max, and we're all still here.
