The LHC operations team and many other experts have been working hard to set up and validate the accelerator for safe beam operation, leading to the first stable beams for physics of 2025 on 5 May

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

The experiment has developed a new device for cooling antiprotons more efficiently and for considerably increasing the precision of measurements of their fundamental properties

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 GBAR experiment at CERN has just joined the very select club of experiments that have succeeded in synthesising antihydrogen atoms

On Friday, 30 June, an exciting milestone was reached: the much-awaited antiproton physics season finally commenced

The AD operations team received on Friday, 1 June – 12 days earlier than rescheduled – the green light from the AD injection kicker expert: beam could be injected again in the AD ring

The beam commissioning of the Antiproton Decelerator will start on 12 June, and the aim is to deliver antiprotons to the eagerly waiting AD-ELENA experiments on 30 June

In the AD hall, a beam of H- ions has reached the GBAR and ALPHA experiments, marking the end of the installation of new transfer lines from the ELENA deceleration ring

The Antiproton Decelerator will see refurbishment work that will help its experiments to trap more antimatter than before

The commissioning of ELENA continued in 2018, culminating in the production of the first very-low-energy antiproton beams
