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…

Beam instrumentation put to the test
Although most of the HL-LHC beam instrumentation work package is well into production and even integration, some of the more innovative designs are also taking advantage of the final beams in Run 3 to test and optimise their performance. In particular, an electro-optical beam position monitor (e-o BPM) and a Beam Gas Curtain (BGC) profile…

Cold Powering System: confidence and validation for future installations, and series production progress
The HL-LHC Cold Powering Systems transfer the current from the power converters, located in the new underground galleries, to the superconducting magnets of the HL-LHC Inner Triplets and Matching Sections, in the LHC tunnel, on either side of Point 1 and Point 5. Eight systems plus two spares of two different types, X for the…
