The Proton Synchrotron (PS) Booster – a key accelerator in the CERN complex – is 40 years old this month

On 16 March beams in the LHC reached the world-record energy of 4 TeV. Stable-beams mode is planned for 3 weeks from now

At 12.38pm CEST this morning, the LHC shift crew declared "stable beams"

In February, Krakow hosted the third International School of Trigger and Data Acquisition (ISOTDAQ), which gives students practical TDAQ experience

With powering tests finished, the LHC is being recommisioned to take beams in the first week of April

The cool-down and circuit testing in all LHC sectors restarted 3 weeks ago, and is going well

CERN's director of accelerators and technology explains the reasoning behind running at 0.5 Tev higher than in 2011

The experiments' desiderata for the year included either discovery or exclusion of the Higgs boson

The first day of the LHC performance workshop was devoted to a critical review of 2011, with suggestions for improvements to the beams and hardware

The final day of the workshop saw examination of the challenges of the High-Luminosity LHC an a look at the state of R&D for the new magnets required
