Watch a timelapse of the unboxing of the first of ten cryo-assemblies from the US to be installed in the HL-LHC interaction regions

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

In about a week, lead ions will be sent from the SPS into the LHC to collide in the accelerator’s four big experiments

The LHC resumes beam production, following the repair of the inner triplet vacuum leak, and gears up for heavy ion collisions

The many CERN-developed sensors and software programs of the FRAS (Full Remote Alignment System) have been successfully tested on a prototype magnet in preparation for the HL-LHC
