Geneva, 31 January 2011. CERN today announced that the LHC will run through to the end of 2012 with a short technical stop at the end of 2011. The beam energy for this period will be 3.5 TeV. This decision, taken by CERN management following the annual planning workshop held in Chamonix last week and […]
From CERN: CERN announces LHC to run in 2012
From CERN: CMS observes a potentially new and interesting effect
After almost six months of operation, experiments at the LHC are starting to see signs of potentially new and interesting effects. In results announced by the CMS collaboration today, correlations have been observed between particles produced in 7 TeV proton-proton collisions. In some of the LHC’s proton-proton collisions, a hundred or more particles can be […]
Textbook tests with tungsten
CERN's linear collider detector group joins forces with CALICE in building the world's first tungsten hadronic calorimeter.
In a hall for test beam experiments at CERN, next to the CLOUD climate experiment and an irradiation facility, sits a detector prototype that is in many ways a first. It's the first ever hadronic sandwich calorimeter (HCal) prototype made of tungsten. It's the first prototype for a detector for the Compact Linear Collider Study […]
From CERN: ICHEP 2010 conference highlights first results from the LHC
Geneva, 26 July 2010. First results from the LHC at CERN1 are being revealed at ICHEP, the world’s largest international conference on particle physics, which has attracted more than 1000 participants to its venue in Paris. The spokespersons of the four major experiments at the LHC – ALICE, ATLAS, CMS and LHCb – are today […]

Celebrating first 7-TeV collisions at the LHC
Director’s Corner 8 April 2010 Barry Barish Celebrating first 7-TeV collisions at the LHC This past week marked the beginning of a new era for particle physics with the much publicised achievement of establishing the first 7-TeV collisions at the CERN Large Hadron Collider (LHC). Both the impressive performance of the accelerator and the fact […]
From CERN: LHC research programme gets underway
Geneva, 30 March 2010. Beams collided at 7 TeV in the LHC at 13:06 CEST, marking the start of the LHC research programme. Particle physicists around the world are looking forward to a potentially rich harvest of new physics as the LHC begins its first long run at an energy three and a half times […]
From symmetry breaking: Demystifying the LHC shutdown
Yesterday the science news media and twitterverse were abuzz following a BBC News article announcing “LHC to shut down for a year to address design faults.” Readers – and the news outlets that frantically re-reported the BBC article – assumed that CERN had found a new problem with the LHC and announced an imminent shutdown. […]
From CERN: Outcome from Chamonix: Better in the long run
Last week, the Chamonix workshop once again proved its worth as a place where all the stakeholders in the LHC can come together, take difficult decisions and reach a consensus on important issues for the future of particle physics. The most important decision we reached last week is to run the LHC for 18 to […]
