CERN Accelerating science

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

Despite challenging working conditions, the vacuum leak caused by the quench that occurred on 17 July was repaired in less than 10 days

Plasma accelerator AWAKE has tested scalability and is all set to begin its second phase of data taking with an upgraded plasma source
