CERN Releases Analysis of LHC Incident
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.'"
When is there ever a guarantee when it comes to electrical? Things frizzle, large areas have no power, cables wear out, the list goes on. 2009? I see this being a long project indeed.
...Physics news make the news!
If one faulty electrical connection (out of several thousands I'm sure), can cause the "largest scientific project on earth" to stall for 6 months, these hyper-intelligent pan-dimensional beings will probably have to wait for as long as Deep Thought did (7.5 million years I believe) to find out that the world has already ended, and they should've stuck to 42
It's too bad that projects like the LHC will soon run out of funding as bankrupt nations concentrate on keeping their populations fed and/or preventing the overthrow of their governments, rather than burning issues like "what is mass, really, when you get down to it?". Of course glitches and malfunctions like this (and the previous ones) will only serve to put us past the point of possibly having been able to answer that question, but failing due to lack of funding.
How many billions of Euros have been spent on this project already?
Seven puppies were harmed during the making of this post.
Well that's not it. Bring me the hydrospanners.
in charge of that component.
And can they make it happen again?
It's worse than I'd thought. They may have to pull quite a few magnets out of the tunnel for repair, and some sheered off their mountings.
There's a lot of energy stored in those superconducting magnets. A magnet quench, where superconductivity is lost, is a violent event, even when the electrical safeties all work properly, as they did here. The magnet heats up suddenly, and boils the liquid helium. That blasts into the vacuum insulation cavity, setting off further quenches in nearby magnets. The pressures were high enough to blow out relief disks (as planned) and damage the vacuum valves to adjacent sections (not expected.).
None of this is about the physics. It's all plumbing and electrical work.
Fools!!! Don't you see? LHC turns on, financial blackhole appears out of nowhere and sucks our banks dry! It's just like in the movies - it's the damned physicists, both at CERN and Wall St. Blood's on your hands, you cretins!
Fuck systemd. Fuck Redhat. Fuck Soylent, too. Wait, scratch the last one.
What really happened is that the LHC destroyed the universe, but then put it back almost the same way as it was before, at least close enough that nobody noticed it.
"But," I hear you ask, "how could the LHC put the universe back together from inside a universe that, speaking rather loosely, did not at the moment exist?"
Well, an equivalent (from an observational standpoint) way of looking at it is that the LHC created a nearly exact duplicate parallel universe at the same time it destroyed the one it was currently residing in. However, it would be totally pointless to create an exact duplicate, otherwise how would you know you actually did it? So it ... left out a bit. Specifically the bit that was containing the liquid helium in LHC'.
It really is one hell of a parlor trick.

Some interns were sucked into a black hole created by the experiment,
but in any undertaking this complex you must expect some minor setbacks.
So they soldier on with a renewed sense of enthusiasm for the mission.
If their machine opens a gateway to hell, I've dealt with that before... I forget where.
Well, back to rejecting software patent applications.
I believe it's actually a problem with the Oscillation Overthruster!
Lord John Whorfin may have tampered with the equipment.
MONKEY BOYS IN THE FACILITY!!!!!!!!
... officials at CERN reassured the scientific community, in high, squeaky voices, that the helium leak will have minimal impact on the LHC program over the long run.
Have gnu, will travel.
Was this.
Sig this!
Fortunately our Safety Inspector was able to assure us that the large electrical arcs and hole in the facility were perfectly okay.
Thank god for that right!

(Intentionally) lost from the antiseptic description of events is a detailed description of what the tunnel actually looked like. Train Wreck. LHC dipoles were ripped from their stands and accordianed like a derailed freight train.
The design flaw which allowed this to happen is a pretty big one; basically there's no "bypass" for current passing between magnets. There needs to be a safe path for current to flow around faults when you open the circuit in a big magnet system, otherwise you get an arc. Not "so" big a deal in a normal conducting system, arcs like we saw here are, as we've seen, catastrophic for cryo cooled accelerators. This design flaw exists between every magnet in the entire 17 mle ring. Fixing it is no small deal.
In spite of what the press release says, there is No Way In Hell they didn't _know_ they were at risk of this failure mode. This was the result of a deliberate decision on their part to minimize the number of penetrations in their magnet cryostats. (All well and good, but claiming it was a surprise is complete bullshit)
MAYBE they can turn on in '09, but they've got a very very big job ahead of themselves.
So they are not saying it was caused by a world gobbling black hole? I bet if they were asked, they would _deny_ it was caused by a black hole. So obviously the problem was caused by a black hole.
And he will be replaced with homer simpson
I found the idea of 'world gobbling' black holes entertaining but why stop at one? If you made more than one, would one consume the other? would they balance? I'm thinking about a car going oh, say the speed of light and you turn on the headlights; does relative time slow down or speed up? did that damned tree fall? is the cat dead? how did Alia get into her grandfathers head?

probably not a problem, probably, but I'm showing a small discrepancy in... well, no, it's well within acceptable bounds again. Sustaining sequence.
If some of the consequences were unexpected, we now know far more about the energies involved in superconducting magnets when they quench. Our knowledge of physics at the extreme end of superconducting magnetism has lept forward by a considerable distance - quite literally, if it was placed on top of one of the magnets.

...it's still the Large Hardon Collider in my mind.
wohooo, world's gonna last a couple more months!
Or maybe it wont come back online till 2012. Bets anyone?
Kidding aside, I will shit myself if this thing isn't running by 2011. Given the state of the global economy, it might get funding cut for awhile. I'm just saying...
Life is not for the lazy.
You remember - the unnecessary war of aggression, waged on false pretences, that most people* found abhorrent?
(*counting non-Americans)
you had me at #!
For better or worse, never underestimate the "communists"... China is just starting to gear up, and a major project that builds on, or stands tall alongside of, LHC will give China plenty of "face" in the world.
Think they just want to spend money on the Olympics?
The Chinese will pick up the slack and lead technology where large capital investments are required, again - for better or worse.

At least the money spent on the LHC has gone do people actually producing stuff, from digging it out of the ground to turning it into useful materials and ultimately into functional objects.
What have the bankers done other than push money around and create derivatives of derivatives that are increasingly detached from any real meaning or value?
Probably the main productive task involved was having extra large pockets sewn into their pants so they could trouser more of the money as it flew on by.
Shouldn't be better to spend billions on some war rather then failed experiment?
Thrilling. Let me know when they accidentally open up a portal to another dimension and evil monsters, hungry for human flesh, comes through.
the should have used these denon thingys throughout the site.
Hell, maybe they did.. It did cost billions after all.
Facebook is a woodpecker tapping on the skull of Humanity, Forever.
The LHC would have cost more if they tried to build it underneath Boston.
There's the plumbers union, the steelworkers union, the garbagemen union, the police, MTA, and a few thousand Charlies to deal with. Not to mention the takeout shops being shut down for a few months at a time.
But hey, they actually built a new Garden. So anything is possible in Boston. Even the Sox winning the Series again. Oh yeah... Well, the Pats winning a Super Bowl. Oh yeah... Well, the Celtics winning the NBA Championship. Like THAT's ever gonna happen again! Yeah! Take That! Bahahahaha!
And if they did build the LHC underneath Boston, it would leak like a sieve. Oh, wait...
deleting the extra space after periods so i can stay relevant, yeah.
Everytime I read 'Large Hadron Collider' I am confronted with what the Internets has done to me. Or am I the only one who's mind automatically flips the d & r?
You never heard of a cold soldering joint before? Tch ...
Much less glamorous than a pesky little black hole penetrating the casing. Or that interdimension portal and shrieking demons.
There weren't any demon carcasses discovered when they got all the helium pumped out, right?
Right?
It is simple to solve world hunger. All we need to do is start feeding plants "Brawndo". Its got electrolytes, which is what plants need.
