Reliability Analysis of the LHC Beam Dumping System

The design of the Beam Dumping System of the Large Hadron Collider at CERN is aimed at ensuring a safe beam extraction and deposition under all circumstances. The system includes redundancy and continuous surveillance for most of its parts. Extensive diagnostics after each beam dumping action will be performed to reduce the risk of a faulty operation upon the subsequent dump trigger. Calculations of the system’s safety and availability are presented for the beam dumping kickers and septa magnets.
