CERN Accelerating science

At its half-way mark, a study investigating the feasibility of a 91-kilometre Future Circular Collider to potentially follow the Large Hadron Collider at CERN shows significant progress

The first beams are already circulating in the Linac4 and PS Booster and should reach the LHC on 11 March. A new physics run is about to begin!

Highlights from this year’s Chamonix workshop, including the crucial role that the injectors play in shaping future research endeavours

Successful tests of the first “MKI-Cool” show that these new kicker magnets can take the heat and keep their cool with high-luminosity beams

The collimation system of the Large Hadron Collider (LHC), which protects the accelerator’s components, needs an upgrade to be able to handle the performance of CERN’s future accelerator

Accelerator highlights, challenges and successes in 2023

Engineers have successfully tested an improved design of a quadrupole magnet manufactured at CERN, confirming that niobium–tin technology is viable for accelerator magnets

The year-end technical stop (YETS) officially started on 30 October, with promising performance tests in Linac4. The injection of the first 2024 LHC beam is scheduled for 11 March 2024

Another few days and the last 2023 LHC beams will be dumped, hopefully by the machine protection system following a controlled magnet quench

Since the last Accelerator Report, lead-ion beams have been successfully provided to the SPS North Area, in particular to the NA61 experiment, which is their principal user

The D2 prototype magnet, developed and manufactured in Italy, has been integrated and tested in the longest HL-LHC cold mass with corrector magnets from China and CERN
