Machine protection: DQHDS series production advances as IT String tests validate HiLumi LHC protection systems
Delivery of Quench Heater Discharge Power Supply (DQHDS) units from KEK is steady, with adaptations being made in response to increased fuel costs. Testing both in Japan and at CERN, and system-level testing in the IT String offer confidence in the technology’s readiness, and for the consolidation of the individually-powered dipole and quadrupole (IPD and

Machine protection: series-production of Quench Heater Discharge Power Supply units well underway
The first batch of 48 series-production Quench Heater Discharge Power Supply (DQHDS) units, provided as an in-kind contribution by KEK, Japan, has just arrived at CERN. These units feature a new design developed by CERN for the HL-LHC upgrade and will operate together with the Coupling-Loss Induced Quench (CLIQ) systems to protect the HL-LHC inner
