Geneva, 18 December 2009. At its 153rd session today, the CERN1 Council heard that the Large Hadron Collider ended its first full period of operation in style on Wednesday 16 December. Collisions at 2.36TeV recorded since last weekend have set a new world record and brought to a close a successful first run for the world’s most powerful particle accelerator. The LHC has now been put into standby mode, and will restart in February 2010 following a short technical stop to prepare for higher energy collisions and the start of the main research programme.
Latest press releases
Geneva, 14 December 2009 Medical studies are soon to start with the MARS scanner, a revolutionary CT scanner developed by the University of Canterbury1, New Zealand. The scanner, which incorporates technology developed at the world’s leading particle physics research centre, CERN2, was recently shipped to research partners in North America. Today a student from Canterbury arrives in North America to use the scanner to study heart disease. This development puts the technology, known as Medipix3, firmly on the path to saving lives.
Geneva, 30 November 2009. CERN1’s Large Hadron Collider has today become the world’s 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 Laboratory’s Tevatron collider since 2001. It marks another important milestone on the road to first physics at the LHC in 2010.
Geneva, 23 November 2009. Today the LHC circulated two beams simultaneously for the first time, allowing the operators to test the synchronization of the beams and giving the experiments their first chance to look for proton-proton collisions. With just one bunch of particles circulating in each direction, the beams can be made to cross in up to two places in the ring. From early in the afternoon, the beams were made to cross at points 1 and 5, home to the ATLAS and CMS detectors, both of which were on the look out for collisions. Later, beams crossed at points 2 and 8, ALICE and LHCb.
Geneva, 20 November 2009. Particle beams are once again circulating in the world’s most powerful particle accelerator, CERN1’s Large Hadron Collider (LHC). This news comes after the machine was handed over for operation on Wednesday morning. A clockwise circulating beam was established at ten o'clock this evening. This is an important milestone on the road towards first physics at the LHC, expected in 2010.
