Repairs to inner triplet magnet in LHC tunnel

This inner triplet magnet Q1 in LHC tunnel's sector 7-8 is being repaired by LHC teams. A quench of the inner triplet magnet caused a small leak and had important consequences. Several superconducting magnets around the LHC quenched – i.e. they lost their superconducting state. Among these magnets were the inner triplet magnets located to the left of Point 8 (LHCb), which play a crucial role in focusing the beams for the LHCb experiment. show Paul Cruikshank, Deputy Group Leader of the Vacuum, Surfaces & Coatings Group, and the final one with his team in the tunnel.
