It's official! The hobbled Large Hadron Collider (LHC) will be up and running again by next summer, according to CERN, the European lab for particle physics where the mighty LHC resides.
The info is part of a new report released today by the agency on the September incident that shuttered the world's largest particle accelerator. CERN determined in October that the LHC was done in by an electrical malfunction shortly after its initial start-up that caused a helium leak in its tunnel.

It's a good indication of the rabid anticipation surrounding the Large Hadron Collider (LHC) that any tidbit about the giant particle accelerator's restart is scrutinized as if it were the Zapruder film. A case in point is a single image from a 52-slide presentation given recently by Jörg Wenninger, a member of the operations group at CERN, the European lab for particle physics, where the LHC sits dormant. (An electrical malfunction that caused a helium leak crippled the accelerator shortly after it came online in September.)
The slide in question provides two scenarios, one in which the LHC starts up again as planned next summer and another in which the beam is not switched on until 2010 to allow for a full upgrade of pressure relief systems. Several blogs made note of the slide, fueling speculation that it would be a full year before the world's biggest science experiment gets under way in earnest. Not true, CERN spokesperson James Gillies told ScientificAmerican.com in an e-mail, insisting that "the LHC will start up in 2009."

The eagerly awaited start-up of the Large Hadron Collider (LHC), the world's largest particle accelerator, has been put off—again. The LHC was shut down in September, just days after being switched on for the first time, when an electrical malfunction caused a helium leak in the collider's tunnel. The repairs, which had been expected to last until spring, will now keep the LHC off-line into early summer, according to published statements from a spokesman for the accelerator's operator.
