How long before it breaks down again? They should have had the Germans build it in the first place.

CERN restarting Large Hadron Collider

The Large Hadron Collider, the world’s largest particle accelerator, is set to restart late Monday following a technical break and a glitch on Saturday.

The first proton beams of 2010 were circulated in the Large Hadron Collider on Saturday, CERN said Monday. The machine had been undergoing technical maintenance for 10 weeks. However, soon after the beams were circulated Saturday, they had to be stopped to allow for maintenance to the cryogenic systems that help regulate the superconducting magnets, according to CERN, which is also known as the European Organization for Nuclear Research.

“Engineers had to access the filters for the cryogenic systems,” a CERN representative said Monday. “They are fixing that, and we expect…beams to be circulating again tonight.”

LHC to restart following break and glitches

The world’s largest particle accelerator is to restart on Monday following a technical break and glitches in the machine.

The first proton beams of 2010 were circulated in the Large Hadron Collider (LHC) on Saturday, Cern said on Monday. The machine had been undergoing technical maintenance for 10 weeks.

However, soon after the beams were circulated on Saturday, the beams had to be stopped to allow maintenance to cryogenic systems which help regulate the superconducting magnets, according to Cern.

“Engineers had to access the filters for the cryogenic systems,” a spokesperson for the organisation said. “They are fixing that, and we expect to beams to be circulating again tonight.”

The beams will be injected at an energy of 450 gigaelectron volts (GeV). The beam energy will be slowly increased until it reaches 3.5 teraelectron volts (TeV) per beam, which is expected to happen in 2 to 4 weeks.

Cern said at the beginning of February that it plans to run the LHC for up to two years at 3.5 TeV, then shut the machine down prior to preparing it to run at 7 TeV per beam.

The LHC has been designed to conduct experiments that will reveal new physics, including proving the existence of the Higgs boson, a hypothetical elementary particle.

The LHC as a project has had mixed fortunes. It was forced to shut down shortly after powering up in 2008 following a helium leak, and was then subject to various delays to its restart. However, when it did start up again in November it quickly became the world’s most powerful particle accelerator, before being halted again for maintenance.

Large Hadron Collider in process of restarting

Scientists are in the process of restarting a giant particle collider built to reproduce the conditions of the big bang, Europe’s CERN physics research center said Friday.

After a year’s delay, the scientists hope to have beams of protons circulating all the way through the Large Hadron Collider’s 17-mile-wide (27-kilometer-wide) underground ring in both directions by early Saturday, and then accelerate them this weekend, CERN spokesman James Gillies said.

“At the moment they’re putting beams down in the Large Hadron Collider, and as the night goes on they’ll take the beams through and start circulating them,” he told Reuters. CERN reported that beams were fully circulating in the clockwise direction, and that preparations were being made to send beams counterclockwise as well.

The experiment will not be properly under way until January when the LHC is operating at a higher level, Gillies said.

Technical problems forced CERN to shut down the $10 billion collider just nine days after it was started for the first time in September 2008.

The problem was a faulty splice in the super-conducting cable connecting two cooling magnets in the underground ring, which smashes particles at a temperature of just above absolute zero to re-create conditions believed to exist at the start of the universe 13.7 billion years ago.

As the particles smash into each other at nearly the speed of light — once the collider is operating at full throttle, which will take several weeks — they will explode in a burst of energy which scientists will monitor for new or previously unseen particles which they predict could help explain the nature of mass and the origins of the universe.

CERN said last year’s accident never posed any danger. The Geneva-based institution has had to rebuff suggestions that the experiment would create millions of black holes that would suck in the Earth.

Okay, so the object of this exercise is to produce a particle collision with enough energy to produce previously theoretical sub-particles, most notably the infamous Higgs boson. Now, my question is, if these sub-particles are, by definition, smaller than anything currently known to man, capable of moving through mass unimpeded, what’s going to contain them as they fly off at the speed of light?
