SCIENCE FTW

[fivecatsnamedfred]

I wish they posted more videos.

If you don't believe me and want to see some of the results for yourself, here is a link to a presentation given by the ATLAS, ALICE, CMS and LHCb teams regarding the experimental data they collected during the 23 days of collisions which started on Nov. 20 (and ended on Dec. 16)

They likely won't be conducting experiments at 7TeV per beam (14TeV collision, its nominal operation performance) until 2011.

They will be conducting physics at 3.5TeV per beam (7TeV collision) starting Feb. 20 2010.

This is 7 times more powerful then any particle accelerator before it, and will yield a lot of new physics.

They will generate a ton of new valuable data in 2010 running at 7TeV collision.

Uh you just said it yourself RESTART, as in start again.

Collisions began on Nov. 23 2009 and were run for 23 days. Over 1 million collision events were performed at 900GeV collision energy, and about 100 000 events were performed at 2.36TeV (new world record in collision energy).

It was put in standby on Dec. 16, and is undergoing nQPS preparation and magnet conditioning for higher amp throughput so they can begin physics at 7TeV collion energy on Feb 20 2010

Dude they said "Restart in February 2010" so it hasn't been started...

[adzii1]

But the machines off untill February hmm it takes about a month-year to get to 7TeV? so it will be around march when they collide at 7Tev?

[mdma4life]

It has already begun, experiments at sqrt(S) of 2.36TeV collision energy have already started (this is more then twice as powerful as any particle accelerator in the past).

Every year in Dec. CERN undergoes a yearly shutdown for maintenance and in this case to prepare the LHC to conduct collisions at 3.5TeV per beam (collision sqrt(S) = 7TeV)

Just thought id update you :P

[adzii1]

yeah and swine flu

[psy0nyd3]

@adzii1 Yeah exactly, The major news networks always use fear tactics. You should know that. Look at how they treated the bird flu......

[adzii1]

Maybe the news is trying to get money by saying it will make black holes ?

[adzii1]

Well people said it might cause at the speed of light with protons colliding might create a black hole but the ydid create ATLAS it prevents black holes and if there was a black hole it willl be unstable and collapse but im still scared :S

Im only 13 :(
