Large Hadron Collider

Volume 485: debated on Tuesday 16 December 2008

To ask the Secretary of State for Innovation, Universities and Skills what recent reports he has received on the operation of the Large Hadron Collider; and if he will make a statement. (242439)

CERN has recently completed its analysis of the incident that occurred in the Large Hadron Collider (LHC) on 19 September which led to a large leak of helium and damage to a number of magnets. CERN has confirmed that the likely cause was a defective electrical connection between two of the LHC's magnets. CERN is now undertaking the necessary repairs to the LHC, and introducing additional precautionary measures so as to avoid further large helium release incidents. The repairs should be completed by end of June 2009.
