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…

IT String: from leak non-conformity observation to first commissioning phase
The IT String is in its operational phase, with many lessons already learnt during the tests so far. The path to this phase – including detection and resolution of a non-conformity, and cooldown – has provided valuable insights and fostered strong collaboration across teams. Leak non-conformity: detection to resolution Following the successful completion of most…

Long Shutdown 3 incoming: installations already heating up in the HiLumi LHC galleries
Since the summer of 2025 installations in the new High-Luminosity (HiLumi) LHC surface buildings and underground galleries at Points 1 and 5, and preparations for de-installation and installation works in Long Shutdown 3 (LS3), have been progressing at a high pace. On the surface, the installation of the cooling and ventilation systems in the SU…
