Large Hadron Collider Struggling

Writing in the NY Times, Dennis Overbye covers the birthing pangs and the prospects for CERN's Large Hadron Collider (which we have discussed numerous times). "The biggest, most expensive physics machine in the world is riddled with thousands of bad electrical connections. [And] many of the magnets meant to whiz high-energy subatomic particles around a 17-mile underground racetrack have mysteriously lost their ability to operate at high energies. Some physicists are deserting the European project, at least temporarily, to work at a smaller, rival machine [Fermilab's Tevatron] across the ocean. ... Technicians have spent most of the last year cleaning up and inspecting thousands of splices in the collider. About 5,000 will have to be redone... Retraining magnets is costly and time consuming, experts say, and it might not be worth the wait to get all the way to the original target energy [of 7 TeV]. Many physicists say they would be perfectly happy if the collider never got above five trillion electron volts. Dr. Myers said he thought the splices as they are could handle 4 [TeV]. 'We could be doing physics at the end of November,' he said in July, before new vacuum leaks pushed the schedule back a few additional weeks. 'It's not the design energy of the machine, but it's 4 times higher than the Tevatron,' he said."

Yes, you can store energy in strained magnetic fields -- so-called "spin batteries". But it's poor energy density. Magnetic "batteries" are still trying to get up to the energy density of supercapacitors, which are in turn still trying to get up to the density of lead-acid batteries, which have been left in the dust by techs like lithium ion batteries. But it's a very new tech, so we'll have to see where it goes.

Sigh, typical American 'work yourself to death' mentality...I say this as an American.....
