Beam Losses, Lifetime and Collimator Hierarchy

The aim of the LHC collimation system is to ensure a safe machine operation; it provides the LHC with passive protection and minimises the risk of magnet quenches induced by beam losses.

Sumario:The aim of the LHC collimation system is to ensure a safe machine operation; it provides the LHC with passive protection and minimises the risk of magnet quenches induced by beam losses. In 2017, the LHC collimation system confirmed its excellent performance, with no magnet quenches due to losses from circulating beams while accommodating changes in machine configurations. The system availability in 2017 was also very good. The present work reviews key elements of the 2017 operation, from initial commissioning with beam to beam losses, lifetime and collimator hierarchy.
