Description
The new Universal Quench Detection System (UQDS) and Protection Device Supervision Units (PDSU) are pivotal elements for the quench protection system of the new HL-LHC inner triplet magnets as well as for requesting a beam dump upon activation of the active quench protection systems, the novel Coupling Loss Induced Quench System (CLIQ) and traditional quench heaters. Given the criticality of these functionalities, a thorough reliability analysis has been carried out to ensure that the probability of critical failures meets the stringent reliability requirements under all operational conditions. To determine the failure probabilities, analytical models were developed that consider redundancies, inspection strategies and demand frequencies. The models’ failure parameters were identified by a component-based Failure Mode and Effect Analysis. The results of the models allow the qualification of the system design as well as insights on critical monitoring and testing requirements of the system when in operation.
