Writing in the NY Times, Dennis Overbye covers the birthing pangs and the prospects for CERN's Large Hadron Collider (which we have discussednumeroustimes). "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."
the setbacks are part and parcel of such a complicated effort
keep up the hard work, you are broadening mankind's knowledge, the expense and the hard work are as valid an endeavour as any other that can be proposed
Agreed. There's a reason the term "cutting edge" is used to describe cutting edge science, and in cutting edge science, well, if it worked perfectly the first time it probably wasn't very ambitious.
Just because it's "cutting edge" doesn't mean it must fail the first time they try to run it for real....
having so many bad joints as part of the reason for failure is a sign of poor workmanship and quality control given the multi-billion dollar budget. It's not a bunch of mad scientists working in their garage on their own dime, it's a bunch of *highly paid* mad scientists using scads of public funds.
I'd give them the "cutting edge" argument if the physics didn't turn out as expected, but bad joints... give me a break.
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.
It wasn't a complement, It was a rational assessment that most American MBA's are stupid assholes, and are almost as bad as their law school brothers, and far too many European Managers _DO_ copy their tricks, which means that you can not trust the quality or integrity of anything they touch. Eg Apple exploding batteries!
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.
One, very obvious, consequence is TAX, in Kanton Zuerich we pay ~ 13% employment tax and 7.6% sales tax, most Kantons are cheaper.
One pass, haul ass, do it RIGHT the first time (a) works, (b) explains the Swiss attitude to quality.
Given the reduced energy: Re, the Higgs Boson (that's the one that everybody talks about): Is that still the one sure thing that this machine will sort out? If the Higgs exists, will they still see it right away, and if it doesn't, will the scientists still finally say, "There is no Higgs, we need new physics to account for why; things have mass, something in our standard model went awry"?
The aim is still to go to 7TeV/beam this is only a temporary reduction in energy. In addition all the evidence so far points to a low mass higgs, not up at the hard ~1TeV/c2 limit where the energy is actually important. This is not unprecedented - the Tevatron which was supposed to be 1TeV/beam ran at 0.8 TeV for the first run and increased it to 0.96 TeV for the second run.
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.

No, it won't. Actually God keeps breaking the LHC. You didn't think (s)he'd let a bunch of monkeys have h(er/is) particle do you?
the setbacks are part and parcel of such a complicated effort
True. But could there be additional complications? To compare it to another grandiose project, the Three Gorges Dam. For starters, it's a prestige project so the Party cannot allow it to fail without losing much face. 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
But the peak current is tens-of-thousands of amps, and the connections are between superconducting cables made of exotic materials, and once the connection is made at room temperature it has to be cooled down by almost 300 degrees (150 times colder than where it started) with all the flexing and stressing that causes, and still can't have more than one or two nano-ohms resistance or the whole experiment blows up.
Yes, the electrical connections in the LHC are the equivalent of rocket science.
Now I just have a picture in my head of the whole thing not working because somebody tripped over the cable connecting the whole thing to the standard wall outlet..
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.
This makes me think back to when I used to play World of Warcraft.
There was a character running around named: "Drphillip" and I thought to myself, "huh, interesting name he has." And then all of a sudden, he started shouting in town:
"OH NOES. teh large hardon collider is turning onz0rz!!!"
I hope they don't settle for running at a lower energy just to avoid criticism about the start date. There is too much potential for what we could discover using the collider's full capacity.
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.
Aside from the electrical connections, the magnets need to be trained to reach the fields necessary to sufficiently bend a 7TeV beam. The last talk I heard on the status of the magnets was that this was a very non-linear effect. We could probably get to 5, 5.5 with not that much difficulty (again, when the electrical connections are repaired)... but even getting to 6 will take *quite* an investment of down-time. The cost/benefit curve has a very clear kink in it.
Real clever of those Tevatron people to masquerade as electricians during the LHC construction. They'll have the God Particle safely in the bag while those upstart Europeans are still chasing their tail.
In recent upgrades to the LHC, the collider has been equipped to smash large amounts of money together and observe its annihilation:
"We start with a 50 Euro note and a 50 USD note," Dr. Grotzy explained. "We accelerate them to near the speed of light- interesting things can happen when the velocity of money gets this high. When the beams of Euros and USDs collide - thousands of notes per minute- we get some interesting reactions.
"This is a photograph of one such collision- an annihilation as you can see," Grotzy said, pointing at the annotated diagram. "The buck stops here."
"Out of it you can see these spiraling particles. Given the $50 is one of the ingredient particles, we call this 'Grant money going down the drain'.
"The experiment is actually quite easy to run. If the beams start to wane you just go up to the generator and throw more money at it.
"To keep busy we'll be adding more projects. With with a little more funding from the Brits, we can test out a heating system powered by burning cash. Convert a pound's mass into energy.
"Some people are concerned this collider will produce economic black holes that will destroy the worldwide economy. I can assure you this is nothing but uninformed rumor.
Here's what's going on: in every universe that the LHC works, the earth immediately disappears in a giant black hole, so, by the entropic principle, we must always be in one of the failures. The project will be plagued with failure until they give up! It's proof positive that we live in a multiverse!
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.
Why does the NYTimes article say things that are out of date, inaccurate and in some cases flat out wrong ? The interview with Myers is dated 2 July but this article [cerncourier.com] from CERN itself dates from the 15th and does not specify any figures for the number of bad connections. They have to run the tests before they know how many bad connections there are, and that hasn't been completed.
So basically this is a fluff piece that takes various peoples statements out of context and tries to promote a problem that CERN itself does not support. Yes it's late, yes there are issues, but the title LHC struggles is hardly warranted.
Yes, you can store energy in strained magnetic fields -- so-called "spin batteries" [sciencedaily.com]. 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.
... best of what's still around. I've noticed a distinct decline in the quality of professional services in the last decade.
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!
Both of your stories are a result of our society telling teenagers that if they want to get ahead, they should go to college, even if their academic skills are no better than average and their trade skills are above average.
Non-illegal, non-meth-head, reliable and competent contractors are extremely rare around here.
It's probably because the "non-illegal, non-meth-head, reliable and competent contractors" were constantly underbid and thus driven out of business by people that would rather save a buck than have it done right.
Don't worry, the Vogons will not be here until 2012. You know that famous Maya calendar? Well, actually it's the timing diagram for the final phase of Earth's computer program.
