Large Hadron Collider Sees First Particle Collisions

- By - Source : Tom's Guide US

We're all still here! It's like some kind of logical Christmas miracle.

The Large Hadron Collider began circulating beams last Friday, and yesterday two beams collided for the first time. The collision is ahead of schedule as the folks at CERN had previously expected the first collision to occur roughly a week after the machine had been restarted. CERN reports that the beams crossed at points 1 and 5, home to the ATLAS and CMS detectors.

"The beams were first tuned to produce collisions in the ATLAS detector, which recorded its first candidate for collisions at 14:22 yesterday afternoon. Later, the beams were optimised for CMS. In the evening, ALICE had the first optimization, followed by LHCb."

"It's a great achievement to have come this far in so short a time," said CERN Director General Rolf Heuer. "But we need to keep a sense of perspective – there's still much to do before we can start the LHC physics program."

Next on the schedule is an intense commissioning phase aimed at increasing the beam intensity and accelerating the beams. If everything goes as planned, by Christmas, the LHC should reach 1.2 TeV per beam, and have provided good quantities of collision data for the experiments' calibrations.

ALICE runs calculations? Is this the precursor to GLaDOS?

Naw... if many worlds interpretation of quantum physics is correct, indeed some quantum realities were annihilated... but you don't know about those ones because you were annihilated with them.... so you are only left experiencing the quantum realities that did not get annihilated.

Please. People who still believe that the LHC will "destroy the earth" really need to study the science behine it.

About time they fired up the big boy. I wonder what kind of data we'll get from a faster collision.
I dont know what there is to be scared of if you read up some of particle collision you'd probably ease your mind a little.

This was a triumph. I'm making a note here: huge success. It's hard to overstate my satisfaction.

Half-Life anyone?

now all we gotta worry about is 2012 which is a good thing cause all the f**ken nut jobs will kill themselves, in 2036 though a comet may strike the earth off the west coast of Los anageles in the pacific ocean, at earths impact it will the 750 feet wide

Nop, I remember the original Half-Life quite well and there was no LHC, or no hadron collider at all for that matter.

First you start with Hadron Coliders then comes with the theoretical physics then comes the Vortigon.

Personally I think I would prefer they not have these little "surprises" but know exactly when stuff is going to happen when it is on this scale.....

Then we get gravity guns and a new frontier in human laziness :D

back_by_demand :
WTF? Is it just me or is the world full of people who just down-right bastardise the English language? Oh, sorry, just the Americans then...DUDE!!! Wake up!!! It's the English language, not the American language. If you want to spell words your own "special way" then stop calling it English./rantI personally hope this LHC program leads the way to huge particle cannons on battleships or attack planes, I heard the beams hit with the force of an aircraft carrier at 100mph. That's what I call a BFG!!!


wow back by demand the quote and your rant seems rather uncalled for... your response is if he was preaching to speak with an American accent is the only English...

partical is just a misspelled particle you dumb ass you know that crap that happens in on-line posting all the time.

hell if anything his misspelling is probably closer to practical then particle

give us a break T_T your "outrage" is nothing but misplaced anger

The collisions thus far have been below 1 TeV, while FermiLab has spend the past 5+ years doing 2TeV collisions... The effects of the LHC are yet to be seen, it won't be used at full power for at least a year.

Next on the schedule is an intense commissioning phase aimed at increasing the beam intensity and accelerating crossing the beams...which could be bad.

Dr. Peter Venkman: I'm fuzzy on the whole good/bad thing. What do you mean, "bad"?

Uhh.. yeah, I was saying they'd misspelled 'particle' without going "z0mg ur retards u spelt it rong", and the irony is that I'm English ^_^ In truth, I don't even know what that guy's rant was about.

I'm tired of waiting to travel through time. Let's pick up the pace, eh fellas?

you already are! Sadly, only in the forward direction, at the same old rate (one second/second last I looked at my watch) :)

Not exactly at 1second/1second

But lets say the inexactitude is very slim.

I, for one, welcome this news. It means my side-business selling specially made micro-black hole resistant tinfoil hats will take off. Available now for the low, low price of 19.95 USD. Everyone needs to get one, unless you don't love your family enough to care about their safety.

Every time i see articles about it i accidentally mis-read it as "Hardon Colider"...
