LHC to run at 3.5 TeV for early part of 2009-2010 run rising later

Geneva, 6 August 2009. CERN's1 Large Hadron Collider will initially run at an energy of 3.5 TeV per beam when it starts up in November this year. This news comes after all tests on the machine's high-current electrical connections were completed last week, indicating that no further repairs are necessary for safe running.

"We've selected 3.5 TeV to start," said CERN's Director General, Rolf Heuer, "because it allows the LHC operators to gain experience of running the machine safely while opening up a new discovery region for the experiments."

CERN and EU Commission agree on closer scientific partnership

Geneva, 17 July 2009. Today in Brussels, CERN1 and the European Commission are to sign a Memorandum of Understanding (MoU), which aims to enhance the long-standing partnership between the two organizations. The MoU will provide a structured framework for cooperation across a broad range of issues of common interest, with emphasis on consolidating and further developing the European Research Area and facilitating the implementation of the European Strategy for Particle Physics, as defined by the CERN Council.

Grids Step-up to a Set of New Records: Scale Testing for the Experiment Programme '09 (STEP'09)

Geneva, 1 July 2009. Preparations are under way for the restart of the Large Hadron Collider (LHC) the world's most powerful particle accelerator. One of the most important systems needed to support the experiments that will utilise this great machine is the global computing grid: the worldwide LHC Computing Grid (WLCG). After months of preparation and two intensive weeks of 24 x 7 operation the LHC experiments are celebrating the achievement of a new set of goals aimed at demonstrating full readiness for the LHC data taking run expected to start later this year.

CERN awarded environmental label

Geneva, 25 June 2009. On 9 June, CERN1 was awarded the "Nature & Economie" label by the Swiss Foundation of the same name, in recognition of its land management on the Meyrin site. The label is awarded to organisations that contribute to biological diversity, and at least 30% of the green areas around buildings have to be managed naturally.

CERN reports on progress towards LHC restart

Geneva, 19 June 2009. At the 151st session of the CERN1 Council today, CERN Director General Rolf Heuer confirmed that the Large Hadron Collider (LHC) remains on schedule for a restart this autumn, albeit about 2-3 weeks later than originally foreseen. Following the incident of 19 September 2008 that brought the LHC to a standstill, a great deal of work has been done to understand the causes of the incident and ensure that a similar incident cannot happen again.
