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: 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 […]
ICHEP opens the LHC era
Director’s Corner 12 August 2010 Barry Barish ICHEP opens the LHC era The 35th International Conference on High Energy Physics The 35th International Conference on High Energy Physics (ICHEP10) held in Paris provided a first glimpse at results from the Large Hadron Collider. The very good control over machine commissioning and the speed at which […]
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 […]
From Symmetry Breaking: Rewriting textbooks and remeasuring the particle data booklet at the LHC
Textbooks were being rewritten during last week’s Physics at LHC conference. “I was sitting in the session, listening to the ALICE talk by Andrea Dainese from Padova on Wednesday morning, and suddenly I knew: I could replace all the textbook bubble-chamber pictures from the sixties in my lectures,” said DESY’s Thomas Naumann, a member of the […]
Keeping ILC costs under control
Director’s Corner 13 May 2010 Barry Barish Keeping ILC costs under control The cost of the project "next-generation linear collider" ILC has been a major issue, ever since we began our ILC design work in 2005. The scale of the project and the costs of the ILC are roughly equivalent to the largest present-day science […]
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 […]
On the threshold of new territory
Rolf Heuer on the physics potential of the LHC's first long run
With stable beams regularly circulating and colliding in the LHC, we have started the physics programme at 7 TeV. At a recent workshop in Italy, participants had the chance to take stock of what lies in store for the LHC’s first physics run. Waiting for collisions in the LHC…Image: CERN Our objective over the next 18 […]
ILC Page 1
What would a central machine operations web page for the ILC look like?
On days when the LHC makes front page news, some web pages get more attention than they usually do. A page that is highly frequented by LHC operators, on display in all control rooms and a favourite link for physicists, but otherwise not all that well known, is LHC Page 1 (aka OP Vistars). One […]
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 […]
