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."

LHC Flips On Tomorrow 526 comments
BTJunkie writes "The Large Hadron Collider, the worlds most expensive science experiment, is set to be turned on tomorrow. We've discussed this multiple times already. A small group of people believe our world will be sucked into extinction (some have even sent death threats). The majority of us, however, won't be losing any sleep tonight."
Reader WillRobinson notes that CERN researchers declared the final synchronization test a success and says, "The first attempt to circulate a beam in the LHC will be made this Wednesday, Sept. 10 at the injection energy of 450 GeV (0.45 TeV). The start up time will be between (9:00 to 18:00 Zurich Time) (2:00 to 10:00 CDT) with live webcasts provided at webcast.cern.ch."

CERN Releases Analysis of LHC Incident 149 comments
sash writes "From the fresh press release: 'Investigations at CERN following a large helium leak into sector 3-4 of the Large Hadron Collider tunnel have confirmed that cause of the incident was a faulty electrical connection between two of the accelerator's magnets. This resulted in mechanical damage and release of helium from the magnet cold mass into the tunnel.
Proper safety procedures were in force, the safety systems performed as expected, and no one was put at risk. Sufficient spare components are in hand to ensure that the LHC is able to restart in 2009, and measures to prevent a similar incident in the future are being put in place.'"

LHC To Start Back Up In November At Half Power 110 comments
mcgrew writes to mention that the Large Hadron Collider, smasher of particles, will get another chance to prove itself this November. The restart will begin with tests at half power, a mere 7 trillion electron volts (TeV), and ramp up slowly to the designed goal of 14 TeV. "Measurements indicate that some of the electrical connections could not safely handle the amount of current needed to run at the full 14 TeV, so will need to be replaced before dialing up the energy that far. But even 7 TeV is much higher than physicists have ever probed in the laboratory before. The Tevatron accelerator at Fermilab in Batavia, Illinois, is the current record holder, with collisions at 2 TeV."

The LHC, the Higgs Boson, and Fate 691 comments
Reader Maximum Prophet sends a piece from the NY Times by the usually reliable Dennis Overbye reporting on a "crazy" theory being worked up by a pair of "otherwise distinguished physicists": that the Large Hadron Collider's difficulties may be due to the universe's reluctance to produce a Higgs boson. Maximum Prophet adds, "This happened to the Superconducting Super Collider in the science fiction story Einstein's Bridge. Now Holger Bech Nielsen, of the Niels Bohr Institute in Copenhagen, and Masao Ninomiya of the Yukawa Institute for Theoretical Physics in Kyoto, Japan, are theorizing that it's happening in real life." "I'm talking about the notion that the troubled collider is being sabotaged by its own future. A pair of otherwise distinguished physicists have suggested that the hypothesized Higgs boson, which physicists hope to produce with the collider, might be so abhorrent to nature that its creation would ripple backward through time and stop the collider before it could make one, like a time traveler who goes back in time to kill his grandfather."

LHC Shut Down Again — By Baguette-Dropping Bird 478 comments
Philip K Dickhead writes "Is Douglas Adams scripting the saga of sorrows facing the LHC? These time-traveling Higgs-Boson particles certainly exhibit the sign of his absurd sense of humor! Perhaps it is the Universe itself, conspiring against the revelations intimated by the operation of CERN's Large Hadron Collider? This time, it is not falling cranes, cracked magnets, liquid helium leaks or even links to Al Qaeda, that have halted man's efforts to understand the meaning of life, the universe and everything. It now appears that the collider is hindered from an initial firing by a baguette, dropped by a passing bird: 'The bird dropped some bread on a section of outdoor machinery, eventually leading to significant overheating in parts of the accelerator. The LHC was not operational at the time of the incident, but the spike produced so much heat that had the beam been on, automatic failsafes would have shut down the machine.'"

I was struck by the craftsmanship and pride that went into trivial things in Germany. For instance, the asphalt on the road doesn't simply get slopped over the concrete curb like in the US... they left a perfect little gap, rarely getting any asphalt at all on the concrete. Then, the tar guy would seal the gap, carefully getting tar only into the gap and very little, if any, on the curb. In the US, they ladle it out without any concern whatsoever about aesthetics.
Of course it was charming, but completely pointless. Nevertheless, it's good to see people take such pride in their craft, and it makes me feel pretty good about other German products.

The implication of that is that you create __TWO__ huge bureaucracies, one in industry, to provide compliance data, and another, in government, to process it. THAT is why the US healthcare system sucks.
This leads to BIG GOVERNMENT, which is already hopelessly corrupt, and for which there is no real check since the pols and media can always fix the result and there is no real limit to government power.
In contrast, the idea of The Good Swiss, who does his job, properly, the first time, on his own, is still strong here. It is like that because people think that is (C) The Right Thing To Do.

Temporarily Lower Energy (Score:5, Insightful)
However, That being said it was never really the case that would would turn the machine on and the Higgs would magically pop out of the ether for all to see. The most likely scenario is a low mass Higgs which decays to b-quarks. Unfortunately the LHC will be EXTREMELY good at producing b quarks from known physic processes (there is even a entire experiment devoted to studying them - LHCb). The result is that a lot of hard, painstaking work will be needed before we can spot the b quarks from a Higgs from background "ordinary" b quarks. Of course there is still a chance that the Higgs might have enough mass to decay to two Z bosons which would be very easy to see early on but, if the Standard Model Higgs exists, the chance looks slim.

True. But could there be additional complications? To compare it to another grandiose project, the Three Gorges Dam.

Second, if there are any technical shortcomings in the design, they will be covered up due to the pressure from on-high. Third, there's theft by contractors in the substitution of inferior materials, allegations of defective workmanship, and so forth. And again, these issues would be covered u

CERN does not have a majority of these under their belt. It might be a difference in how they are managed. Perhaps Fermilab has a better hierarchy, better safety rules and prioritizes work more efficiently. Maybe they actually triple check each wire before they press the On button and CERN cuts corners. This is all supposition, but reality is a harsh mistress and it is obvious they're doing something wrong.
Clearly you must me be a theoretical physicist, as opposed to a experimentalist, because that explanation was really complicated and stuff, although it did lack the required theoretical physicist collection of complicated equations.
The experimentalist physicist explanation is, as usual, much simpler, the LHC has more recent news reports about failures than the Tevatron, because the LHC was first run in late 2008, and the tevatron was completed in 1983, somewhat before the birth of a typical grad student, so all the news reports about tevatron teething problems were more than a quarter century ago, and long forgotten.

If it is at all feasible to get this running at or near 100%, it's worth it to put in the time now to fix it. I'd rather wait another year now, then wait 30+ years for the next accelerator to be built.

If we ever are to control things like gravity and other exotic properties of spacetime it will be with insight and knowledge gained through particle physics theory and experimentation. Sometimes I wonder what discoveries we turned our backs on by cancelling the Superconducting Supercollider that was to be built in Texas. It was cancelled in 1993 in the face of cost overruns. When you look at the history of that project, however, it's clear that it NEEDED to be cancelled. It had become a black hole for money because of design and construction cost overruns. It was more out of control than any strange particles it might have produced. I hope the Large Hadron Collider doesn't suffer the same fate, but it doesn't bode well for the future when the overall design and QC on the manufactured components are now being called into question. Sad. When ambitious projects such as these founder it's usually their own fault.

Unrelated. The LHC failures have all been caused by unforeseen consequences of standard techniques applied in completely unique situations or new techniques developed to suit the situation. When you are doing something that has literally never, ever been done before things like this are common. Prior experience can only take you so far after that you are learning how to do the thing because you are the first person to ever do it. This is a far cry from installing a sink or rewiring a house which has been done thousands of times before and for which the ways in which it can fail are well known and can be avoided.
The people involved in the work are not just a few plumbers and electricians that were called up from the local yellow pages (or Pages Jaunes at CERN) but are either CERN employees or employers of contractors. My experience has been that while they are extremely "union" orientated (they are very particular about their breaks, starting/stopping work etc) they are also extremely professional to the point where they have come and shown be the right way to do something so it did not make their work look unprofessional!
