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.

University of Geneva honours LHC project leader at 450th anniversary ceremony

Geneva, 5 June 2009. The University of Geneva is today holding a ceremony at which honorary degrees will be bestowed on four figures renowned for their activities in bringing nations together, including international collaboration in scientific research at CERN1.

The ceremony is to celebrate the university’s 450th anniversary2. The honorary degrees, which recognize endeavours in human rights and in fostering dialogue between nations, are being awarded to Mary Robinson3, Desmond Tutu4, Pascal Lamy5 and Lyn Evans.

Austrian participation in CERN

Geneva, 11 May 2009. This afternoon, a meeting took place in the Ministry of Science and Research in Vienna between Austrian Science Minister Johannes Hahn, CERN1 Director-General Rolf Heuer, and CERN External Relations Coordinator Felicitas Pauss. In a constructive working meeting, Minister Hahn explained the reasons for wishing to end Austrian membership of CERN at the end of 2010.

Final LHC magnet goes underground

Geneva, 30 April 2009. The 53rd and final replacement magnet for CERN's1 Large Hadron Collider (LHC) was lowered into the accelerator's tunnel today, marking the end of repair work above ground following the incident in September last year that brought LHC operations to a halt. Underground, the magnets are being interconnected, and new systems installed to prevent similar incidents happening again.

CERN launches new youth site on Web’s 20th anniversary

Geneva, 13 March 2009. Web veteran Robert Cailliau today launched CERNland, a new website for young people, on the occasion of the Web’s 20th anniversary. CERNland has been developed to bring the excitement of CERN’s1 research to a young audience aged 7 to 12 through a range of films, games and multimedia applications. It is available at

“I’ve been involved with CERNland from the start,” said Cailliau, “and It’s great to see CERN using the Web to reach out to a young audience.”

CERN celebrates 20th anniversary of World Wide Web

Geneva, 13 March 2009. Web inventor Tim Berners-Lee returned to the birthplace of his invention today, 20 years after submitting his paper ‘Information Management: A Proposal’ to his boss Mike Sendall. By writing the words ‘Vague, but exciting’ on the document’s cover, and giving Berners-Lee the go-ahead to continue, Sendall was signing into existence the information revolution of our times: the World Wide Web.

Hollywood comes to CERN

Geneva, 12 February 2009. CERN1 today hosted a visit from actors Tom Hanks and Ayelet Zurer and director Ron Howard as they unveiled exclusively some select footage from their new film adaptation of Dan Brown’s novel Angels & Demons, set for worldwide release by Sony Pictures on 15 May 2009.

When Sony Pictures first contacted CERN early in 2007 about filming part of Angels & Demons there, the laboratory quickly saw an opportunity and was excited to participate.

CERN management confirms new LHC restart schedule

Geneva, 9 February 2009. CERN1 management today confirmed the restart schedule for the Large Hadron Collider (LHC) resulting from the recommendations from last week’s Chamonix workshop. The new schedule foresees first beams in the LHC at the end of September this year, with collisions following in late October.  A short technical stop has also been foreseen over the Christmas period. The LHC will then run through to autumn next year, ensuring that the experiments have adequate data to carry out their first new physics analyses and have results to announce in 2010.
