LHC news : LHC beats world energy record!

Date- 30th Nov 09 Source- http://cdsweb.cern.ch/collection/Video%20Movies

'Geneva, 30 November 2009. CERN1s Large Hadron Collider has today become the worlds highest energy particle accelerator, having accelerated its twin beams of protons to an energy of 1.18 TeV in the early hours of the morning. This exceeds the previous world record of 0.98 TeV, which had been held by the US Fermi National Accelerator Laboratorys Tevatron collider since 2001. It marks another important milestone on the road to first physics at the LHC in 2010. We are still coming to terms with just how smoothly the LHC commissioning is going, said CERN Director General Rolf Heuer. It is fantastic. However, we are continuing to take it step by step, and there is still a lot to do before we start physics in 2010. Im keeping my champagne on ice until then. These developments come just 10 days after the LHC restart, demonstrating the excellent performance of the machine. First beams were injected into the LHC on Friday 20 November. Over the following days, the machines operators circulated beams around the ring alternately in one direction and then the other at the injection energy of 450 GeV, gradually increasing the beam lifetime to around 10 hours. On Monday 23 November, two beams circulated together for the first time, and the four big LHC detectors recorded their first collision data. Last nights achievement brings further confirmation that the LHC is progressing smoothly towards the objective of first physics early in 2010. The world record energy was first broken yesterday evening, when beam 1 was accelerated from 450 GeV, reaching 1050 GeV (1.05 TeV) at 21:48, Sunday 29 November. Three hours later both LHC beams were successfully accelerated to 1.18 TeV, at 00:44, 30 November. I was here 20 years ago when we switched on CERNs last major particle accelerator, LEP, said Accelerators and Technology Director Steve Myers. I thought that was a great machine to operate, but this is something else. What took us days or weeks with LEP, were doing in hours with the LHC. So far, it all augurs well for a great research programme. Next on the schedule is a concentrated commissioning phase aimed at increasing the beam intensity before delivering good quantities of collision data to the experiments before Christmas. So far, all the LHC commissioning work has been carried out with a low intensity pilot beam. Higher intensity is needed to provide meaningful proton-proton collision rates. The current commissioning phase aims to make sure that these higher intensities can be safely handled and that stable conditions can be guaranteed for the experiments during collisions. This phase is estimated to take around a week, after which the LHC will be colliding beams for calibration purposes until the end of the year. First physics at the LHC is scheduled for the first quarter of 2010, at a collision energy of 7 TeV (3.5 TeV per beam).'

boobs and accents! what more could we ask for..... thank you cern!

[baf4redrum]

thanks for this contribute and update

I find really absurd that in a post concerning Physical themes , such comments might be allowed on "accent" or even worse, if I were the author of this post I would sincerely reject similar comments,above all for how they have been expressed, anyway I found the presentation by the minute-person absolutely clear and understandable

[hyperstone6]

In addition for answering the ultimate question they got HOT chicks! What a WIN!!

[nasanasa3]

i paused my deadmau5 for THIS?!

[marck079]

"the -MOST- powerful" I wanted to say more exactly, sorry

[marck079]

quite wide of a science channel, this seems rather something more like a glamour blog or something in the same style, considering all the dump idiot comments I had unfortunately to cross against below, what the hell might "accents" or even worst things got to do with energy and beams etc.!? - thanks anyway for the upload (I guess however, it was quite clear that LHC was the powerful accelerator,27 kms lenght indeed are not a joke at all....)

but will it blend?

[Atamv]

@bonsaiiiiii Haha. Jealous some people actually do something useful?

[alphadexxa]

i have a question, it is me or is the only thing they are doing is breaking records? where the experiments and results?

[Expertuzo]

@29Gixxer ohh yeaa, noone can compete with their mouths and theyre crazy tempers.. :P

[Expertuzo]

@29Gixxer too bad english women arent.
