First beam in the LHC - accelerating science

Geneva, 10 September 2008. The first beam in the Large Hadron Collider at CERN 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.

Start-up fever

Unusually for the holiday season, the car parks are full, finding a table at lunch is a formidable challenge, and people can (more than ever) be found in their offices late into the night. All the evidence points to one thing… the most ambitious particle collider in the world is just a few weeks away from its first proton beam!
