New collimators for HiLumi LHC: pre-series paving the way to full production
Teams at CERN are working hard to perform essential tests on three pre-series collimators to validate their new designs and give the final green light for the full series production for the High-Luminosity LHC (HiLumi LHC). The pre-series includes a more-traditional single-beam collimator and two new X-series collimators which feature a double-beam design, new for…

First series RFD crab cavity on the road to cryomodule assembly
The first dressed series RF dipole crab cavity, RFD02, has been successfully delivered to TRIUMF, Canada, from JLAB, USA. This begins the cavity’s journey towards cryostating, when it will be integrated – along with the second dressed series cavity expected to arrive still in the first half of 2026 – into the first series cryomodule.
