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 successfully transported a box filled with unbonded protons across CERN’s main site, thus demonstrating that the same feat could later be possible for antiprotons

Walter Oelert led the team of researchers who produced the world’s first atoms of antihydrogen in 1995

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

With the Proton Synchrotron and its Booster accelerating protons to high energies again, the physics season can start at the ISOLDE radioactive ion beam facility and the Antimatter Factory
