LHC Offline Until April 2009 (Or Longer)
rufey writes "The recent problems at the Large Hadron Collider will now keep it idle until spring 2009. The official press release is here. The LHC went offline due to a suspected failure in a superconducting connection, which overheated and caused around 100 of the LHC's super-cooled magnets to heat up by as much as 100 degrees. This resulted in the accidental release of a ton of liquid helium. The process required to repair the failed superconducting connection involves weeks of warming up the affected area from -456 degrees Fahrenheit to room temperature, and then several more weeks to cool it back down after the repair is made. The total amount of time to do this will spill over into CERN's scheduled winter maintenance/shutdown period, which is partly done to save money on electricity during the period of peak demand."
I can wait till next spring for the world to end.
Now where did that paper clip go?

That sucks.
I remember reading an article on here talking about a theory in which a particle from the future could come back and shut things down. I guess they could use that theory for any kind of downtime though.

Great, so we won't have to hear more stories about the end of the world caused by black holes. Well, at least until the spring anyway.
This breakdown is probably just the beginning of a series of breakdowns. A year from now everyone will be complaining about the huge price tag on this thing that has never been 100% operational.

I spent all my money over the last 6 months on alcohol and parties, secure in the knowledge that the world would come to an end this October when the LHC came up to full power.
This is unacceptable. I demand they destroy the world now.
I'm a big tall mofo.
I believe with all the problems they're having, the actual date when the high-energy collisions begin will be December 2012.
Say something meaningful--the magnets were about 2 degrees Kelvin.
Do they actually mean there was a metric ton of Liquid Helium released, or just a lot? I mean, any liquid helium spilled, even jus a measly ounce, to me seems like a big deal considering how expensive and, well, cold it is. A whole ton? Seriously, is this an actual figure or is it just an exageration? Or is it even an understatement? I really have no idea.
Or something more sinister? Did they make a blackhole? Are they desperately trying to contain it before it destroys the earth?
Although really, if my ST:NG watching is any indication, coolant leaks are bad mojo in and of themselves. And that would explain why I was told to put on a red shirt this morning.
Mod me down with all of your hatred and your journey towards the dark side will be complete!
Holy FSM! More or less 31 weeks of downtime. Anyone have more details about the warming up and cooling process? I mean, how efectivly is it done and how long it take for each sector?

the BIGGEST and probably the most important experiment ever conceived is underway, and they are being left to think about saving energy ?
if there is anything that world shouldnt be saving energy, if there is anything that needs to be subsidized by governments, this is it.
because, this is IT. if the god particle is found, the smallest block of EXISTENCE will be found.
im appalled how EU is not being of sufficient assistance in this. unbelievable.

you mean 2 Kelvin (since it is an absolute scale)
Hey old chap, can tell me the length in barleycorn's for this collider?
Last time I checked, LHe was about $5 USD a liter. A metric ton is 1000kg, and LHe's density is 0.125g/ml (wikipedia), which amounts to 8000 liters or about 40k. Considering that He is non-renewable, leaking out of the atmosphere, hopefully they were able to reclaim and recompress it.
They must be calling the black hole firefighters. as everybody knows this stuff grows slowly: http://www.channel4.com/news/articles/science_technology/black+hole+missing+link+found/2459102 "super-massive black holes were thought to grow slowly". Way to go, that'll learn us to put such a facility in switzerland where suicide rates are so high.
A ton of helium! What's the big deal? That's, like, way lighter than a ton of air!
[I'm being facetious about the weights, but in terms of cost, losing a ton of helium is freakin' expensive]
Look at the LHC cyro status for sector 3-4. Average magnet temperature is now at 70K, and slowly creeping up to room temperature. Notice the expanded vertical scale on the graph. Compare with the other sectors, holding with liquid helium at 1.9K.
Warmup is slow. Cooldown is slower. Several kilometers of pipe and a hundred or so magnets are involved.
It's not that bad, though. It looks like they won't have to take magnets out of the tunnel for rewinding. That's a huge job. This is just a slow one.
They can warm up or chill down sector 3-4 during the shutdown period. The rest of the system would normally be cooled during shutdown anyway.
Quit complaining about Fahrenheit, we could have said 2.7 Rankine.
I could claim that I was born before the 13th General Conference on Weights and Measures and exhort you to get off my lawn...but I'd be lying.
I, for one, welcome the Higgs bosons from the future that successfully interfere with the LHC in the present!
Yikes, I'd be more worried about the liquid helium being released than making a black hole. You'd die awfully quick if your precious oxygen is replaced with helium.
Okay, I'm a born and raised American, and -453 Fahrenheit means nothing to me. Even us Americans use Celsius for science. If I read a temperature outside of what the weatherman could report, then a Fahrenheit measurement is just another number that I have to convert before it will mean something. (Let's see... being a former Clevelander, the weatherman range would be from about -30 to 110 F.)
Please. If it's science, give us our 'degrees C'.

That actually is appropriate, though probably not in the sense that P means. The Mesoamerican calandar that 'ends' in 2012 is just the end of a chunk of a calendar, to be followed by another chunk, and another, etc. It is like New Year's Eve for us; the end of a cycle and an excuse to party. 2012 is just an excuse to party, Mayan style, ripping the hearts out of human sacrifices or however they celebrate it.
When the first collisions happen, that will be grounds for partying also.
maybe it sent particles thorugh space time and they are tugging some giant galactic cluster toward it and in a giant wormhole it will all pop back here. /me gets some popcorn ( not from a movie theatre )
It sure is a good thing that they have 30-40 spare magnets.
To upgrade to XP.
Turns out one of the new particles forgot to get certified Vista-ready.
Not naming any names here (I'm looking at you muon-antineutrino!)
It was a mini black hole that eat through the insulation! No question about it... now it is busy devouring the Alps, then Europe (sell sell sell all your Euros, now!). It will then gradually expand and eat Wall Street (wait! it has happened already!). The world will come to an end before they can fix this machine.

They will trun it back the day after the CUBS win it all.
That does not suck. But the alternative...
Ok, I've made a LHC black hole joke. I couldn't resist... Shame on me :(
Rethinking email
Real scientists use SI metric base units. And as everyone knows, the SI unit for temperature is... *drumroll*...
KELVINS.
I bet the LHC won't be fully operational until 2012. I'd say around December.
It's left blank because I have nothing to say to you punks!
I bet there'll be more delays and it will be fully functional on Dec 21, 2012.. By that time, i'll have enough canned food, bottles of fresh water and a little boat, sailing in the south atlantic :D

My guess is that the first collision will take place this winter while it's supposedly shut down.
THEY don't want all the publicity when they start it up.
THEY want to control whatever powerful new technologies may come out of it.
THEY killed Elvis and Emilia Earhart, and hide the secret to cold fusion and the low-fat cheeseburger.
Common Sense isn't as Common as people think...
I wonder if anyone has considered the dangers of that much free helium. If there was a horrible accident at LHC if they called anyone their voices would be too high pitched to take seriously.
They will trun it back the day after the CUBS win it all.
Against Miami?
Yeah. Who would've thought? 100 to 1 shot! I wish I could go back to the beginning of the season, put some money on the Cubs.

I am the richest astronaut ever to win the superbowl.
In this story a superconducting supercollider had a similar accident, although the results were much different. Good read.
I hope the repairmen don't forget their gloves or screwdrivers in there.
More seriously: the LHC wasn't designed with repairability/serviceability in mind, it seems. Before you mod me down: the proof is before our eyes!

This is terrible. I may actually have to consider who I'm voting for in the upcoming US Presidential elections.... I DEMAND THAT THEY RESTART THE LHC... IMMEDIATLY!!!
I am dissappointed. We are on slashdot. Please say instead
"The results will be evalutaed using GNU/Hurd"
or "The operators could finish a round of DNF in the breaks" or "a microsoft linux running on phantom game consoles is used as a thin client operating system" etc...

Give me my degrees Rankine!
And then I'll have a side of Kelvin too. Thank you.
But seriously, what about space suits? They allow people to survive in absolute 0. Why can't they be used?
Cubbies i thought...or am I wrong?
I thought they could, like, warp the firmament or woof the continuum or something. Can't they fix it yesterday?
Flamebait? Sheeesh, lighten up mods. Well, one mod in particular, I suppose.
...the future crusty old bastards are already drinking the Kool-Aid.

Sorry, couldn't resist.

Yeah, but the shark still looks fake.
Sounds like weeks of fun ahead, mopping up a ton of evaporating helium, chatting along like a flock of canaries. No really...
The aliens put top priority into making sure that the collider did not come online and seed a black hole.
Interestingly enough, the aliens' normal work centers around stabilizing the worldwide financial markets. That work obviously suffered while they were preoccupied. It is taking some time for them to get back on track, too.
They are *quite* heavy in a gravity well.
There is a war going on for your mind.
The absolute zero of empty space is a much different situation than the absolute zero of the collider.

The repairs are going to take a long time. A blck hole formed and time moves real slowly down there now. Good new is the technicians get paid in uphole time.
Squirrel!
Spacesuits operate in vacuum, which means there are almost no no particles around, so the word temperature does not make much sense there. Vacuum is an excellent insulator, so it is easy to keep them warm. It is a myth that you instantly freeze when exposed to the vacuum of space.

First it was socks, now it's liquid helium cooled super conducting magnetic insulators. What's next?!
That particular bloke is from the Deep Time Agency.
Yeah, just dump in a bin of photons and electrons instead of protons and bounce those around section 3-4. Should warm up nicely.
Can this explain the reason for the setback?
"the paper suggested that future effects caused by the production of particles, such as the Higgs, could ripple backwards in time and prevent the LHC from ever operating."
Hey baby, I have a Large Hardon Collider in my Pants, and it wants to look into black holes. Heh.
There, fixed that for you
I propose in all the other parallel universes, the LHC is activated and destroyed humanity. Thus the one *I* am in, the LHC will never work.
Or it will work, but only give bland results.
Hm. Now there's a thought. --Your safety and continued existence requires that certain otherwise possible realities never manifest. The very fact that you are aware forces the universe into a stable state so that you can remain aware.
Might explain a great deal.
Of course, in MY version of reality, you're just another Red Shirt. I'm sorry. I'm so, so sorry.

I just got off the phone with one of the network engineers at CERN, they expect to have the whole thing up and running again by Dec 21st, 2012, nothing to be alarmed about here, people tend to read into things way too much :)
I wonder whether the guys who hacked into the LHC a few weeks back had a better ride than the CERN guys want to admit???
to code or not to code, that is the question.
