The Large Hadron Collider (LHC) at the European Organization for Nuclear Research, CERN, in Switzerland is one of the world’s largest and most complicated machines. Since 2009, CERN has engaged CSL to perform technical audits of the LHC Beam Interlock System and the LHC Beam Loss Monitoring System - both of which lie at the heart of CERN's approach to the protection of the LHC. 

These audits covered a wide spectrum of considerations ranging from very high speed micro-electronics to human factors. CSL has also contributed to the specification of detailed functional requirements for another system with an integral role in the protection of the LHC machine. Most recently, CSL collaborated with CERN on a project involving the specification and design of an interlock system for the protection of supercooled magnets used to confine plasma in a thermonuclear experimental reactor.
