EPS celebrates 40th Anniversary

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.

LHC re-start scheduled for 2009

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.

Incident in LHC sector 3-4

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.

First beam in the LHC - accelerating science

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.

CERN reiterates safety of LHC on eve of first beam

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.

CERN announces start-up date for LHC

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.

CERN Council looks forward to LHC start-up

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.

Saudi Arabia and CERN sign Protocol to Cooperation Agreement

Geneva, 9 May 2008. A Protocol to the 2006 Cooperation Agreement between Saudi Arabia and CERN was today signed at CERN by H.E. Dr. Mohammed I. Al-Suwaiyel, President of the King Abdulaziz City of Science and Technology, on behalf of the Government of Saudi Arabia, and Robert Aymar, Director General of CERN1, in the presence of H.E. Ali I. Al-Naimi, Minister of Petroleum and Mineral resources and Chairman of the Board of Directors of Saudi Aramco, H.E. Dr. Ibrahim A. Al-Assaf, Minister of Finance and a delegation of representatives of Saudi universities and Saudi Aramco.

CERN opens its doors to the world

On 6 April 2008, CERN1 will open its doors to the public, offering a unique chance to visit its newest and largest particle accelerator, the Large Hadron Collider (LHC), before it goes into operation later this year. This scientific instrument, the largest and most complex in the world, is installed in a 27 km tunnel, 100 metres underground in the Swiss canton of Geneva and neighbouring France. CERN will open all access points around the ring for visits underground, to the tunnel and the experiment caverns.

ATLAS completes world’s largest jigsaw puzzle

Geneva, 29 February 2008. Today the ATLAS1 collaboration at CERN2 celebrates the lowering of its last large detector element. The ATLAS detector is the world’s largest general-purpose particle detector, measuring 46 metres long, 25 metres high and 25 metres wide; it weighs 7000 tonnes and consists of 100 million sensors that measure particles produced in proton-proton collisions in CERN’s Large Hadron Collider3 (LHC).
