Geneva, 16 October 2008. Investigations at CERN1 following a large helium leak into sector 3-4 of the Large Hadron Collider (LHC) tunnel have confirmed that cause of the incident was a faulty electrical connection between two of the accelerator’s magnets. This resulted in mechanical damage and release of helium from the magnet cold mass into the tunnel.

Geneva, 3 October 2008. Today, three weeks after the first particle beams were injected into the Large Hadron Collider—the world’s largest particle accelerator—the Worldwide LHC Computing Grid celebrates the start of its crucial data challenge: the analysis and management of more than 15 million Gigabytes of data every year, to be produced from the hundreds of millions of subatomic collisions expected inside the LHC every second. This data-handling feat marks an essential stage in the process of enabling researchers to discover new physics.
Geneva, 2 October 2008. Following the successful circulation of first beam in the LHC on 10 September, the world’s largest and most complex scientific instrument will be officially inaugurated at CERN1 on 21 October 2008. Representatives of the governments of CERN’s Member and Observer States and other participating nations have been invited.
The LHC's start-up day went very smoothly, with the first beam being threaded around the ring to great acclaim in just under one hour.
Geneva, 26 September 2008. Exactly 40 years ago today, the European Physical Society1 (EPS) was founded at CERN2 to promote physics in Europe. Today, the EPS represents over 100,000 physicists from 40 national member societies, thus reaching well beyond the geographical area covered by the European-Union. Maciej Kolwas, EPS President elect, stated that not only is physics the basis of much of today’s technology, it was indeed at the forefront of building a united Europe and remains an integral part of human culture.
Geneva, 23 September 2008. Investigations at CERN1 following a large helium leak into sector 3-4 of the Large Hadron Collider (LHC) tunnel have indicated that the most likely cause of the incident was a faulty electrical connection between two of the accelerator’s magnets. Before a full understanding of the incident can be established, however, the sector has to be brought to room temperature and the magnets involved opened up for inspection. This will take three to four weeks. Full details of this investigation will be made available once it is complete.
Geneva, 20 September 2008. During commissioning (without beam) of the final LHC sector (sector 3-4) at high current for operation at 5 TeV, an incident occurred at mid-day on Friday 19 September resulting in a large helium leak into the tunnel. Preliminary investigations indicate that the most likely cause of the problem was a faulty electrical connection between two magnets, which probably melted at high current leading to mechanical failure. CERN ’s strict safety regulations ensured that at no time was there any risk to people.
Geneva, 10 September 2008. The first beam in the Large Hadron Collider at CERN1 was successfully steered around the full 27 kilometres of the world’s most powerful particle accelerator at 10h28 this morning. This historic event marks a key moment in the transition from over two decades of preparation to a new era of scientific discovery.
“It’s a fantastic moment,” said LHC project leader Lyn Evans, “we can now look forward to a new era of understanding about the origins and evolution of the universe.”
Geneva, 5 September 2008. A report published today in the peer reviewed Journal of Physics G: Nuclear and Particle Physics1 provides comprehensive evidence that safety fears about the Large Hadron Collider (LHC) are unfounded. The LHC is CERN’s2 new flagship research facility. As the world’s highest energy particle accelerator, it is poised to provide new insights into the mysteries of our universe.
Geneva, 7 August 2008. CERN1 has today announced that the first attempt to circulate a beam in the Large Hadron Collider (LHC) will be made on 10 September. This news comes as the cool down phase of commissioning CERN’s new particle accelerator reaches a successful conclusion. Television coverage of the start-up will be made available through Eurovision.
Geneva, 20 June 2008. At its 147th meeting in Geneva today, the CERN1 Council heard news on progress towards start-up of the laboratory’s flagship research facility, the Large Hadron Collider (LHC). Commissioning of the 27-kilometre LHC began in January 2007 when the first cool down of one of the machine’s eight sectors began. Today, five sectors are at or close to their operating temperature of 1.9 degrees above absolute zero and the remaining three are approaching that temperature.
