| Abstract | The Quench Heater Discharge Power Supplies (HDS) are magnet protection devices installed in the Large Hadron Collider (LHC) that, upon detection of a magnet quench, release energy into strip heaters that are in thermal contact with the superconducting coils, inducing a resistive transition all along the coils. The new HDS design for protection of the High Luminosity LHC (HL-LHC) Inner Triplet magnets calls for a more advanced design with up-to-date components resulting in a high reliability of the HDS units. Several HDS prototypes were produced at CERN, eventually culminating in the development of the HL-LHC HDS version to be installed in the accelerator. This paper describes the design of the upgraded HDS units and the comprehensive safety and electromagnetic compatibility (EMC) tests conducted, coupled with an assessment of readiness under extended operational conditions, including irradiation tests. |
