The four accelerators that feed into the Large Hadron Collider have all been restarted, while the LHC itself will receive its first particles on 4 April

The recommissioning of the accelerators is progressing according to schedule. Unsurprisingly, some issues have arisen, but they have been swiftly addressed by equipment experts. First physics in the PS East Area and n_TOF is scheduled to start next week

While the first H⁻ ion beams have been accelerated up to 160 MeV in Linac4, the PS Booster is preparing for its first proton injection of 2025

Although the much-appreciated winter break is well behind us and most of us are back at work, the accelerator complex is still in hibernation – but not for much longer

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

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

The LHC injector chain has been switched to a new beam production scheme to explore its potential to produce more collisions in the LHC and to compare its performance to that of the standard LHC beam

The LHC is performing well and the injector complex is treating its experimental users to a high level of beam availability

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

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!
