Soon, CERN personnel will take a well-deserved winter break, just like the accelerator complex. Following a successful year, the remainder of the accelerator complex was stopped on 2 December, marking the official start of the year-end technical stop

Lead-ion physics at the LHC and the SPS North Area is already under way and progressing well. The final lead-ion user in the PS East Area started its physics run on 13 November

As the LHC and SPS wrap up their 2024 proton run, teams are making final preparations for the lead-ion physics run starting on 4 November

CERN’s accelerators show very good availability rates: beams are in place

Ted Wilson was involved in the design of the Super Proton Synchrotron (SPS) and played a leading role in its commissioning

Restarting the entire accelerator complex after a technical stop is rarely seamless and often comes with unexpected technical challenges

The NA64 collaboration has used a muon beam for the first time to search for dark matter and could set new limits for a potential dark Z' boson

Almost the whole accelerator complex is now in “physics mode”, routinely delivering the various types of beam to the different physics facilities and experiments. Notably, the intensity ramp-up in the LHC is progressing remarkably well

For the first time, scientists at CERN, in collaboration with scientists at GSI, have been able to measure a coupled resonance structure that may cause particle loss in accelerators

The injection of the first protons into the LHC is scheduled for 11 March, but could be brought forward by a few days if all goes well

A new physics run is about to begin! The first particle beams should reach the Large Hadron Collider (LHC) on 11 March

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!
