The crab cavities, a new technology to brighten up the future, will play an important role in the High-Luminosity LHC
Before the LHC was shut down for the winter, the operators tested techniques under development for its successor, the High-Luminosity LHC (HL-LHC)
CERN is helping to align and test a 350-metre column to produce extra-pure argon for a dark-matter search experiment
During the 2017 LHC special runs, the LHCb experiment collected proton-proton and proton-neon data simultaneously for the first time
The last components of AWAKE – its electron source, electron beam line and electron spectrometer – have just been installed
At 10:50 yesterday morning, scientists at the pioneering SESAME light source saw First Monochromatic Light through the XAFS/XRF spectroscopy beamline, signalling the start of the laboratory’s experimental programme.
CERN was the guest of honour at the Automnales, Geneva’s huge annual fair: ten days of encounters and exchanges with the general public.
Steven Weinberg’s iconic paper, A Model of Leptons, was published in 1967 and determined the direction for high-energy particle physics research
The LHC’s 2017 proton run has ended with record luminosity. The special runs will now take place before the winter shutdown.
CERN, the International Cancer Expert Corps (ICEC) and STFC are developing medical linear accelerators for low- and middle-income countries
We meet some of the Marie Skłodowska-Curie fellows, on the 150th anniversary of the exceptional scientist’s birth
During a seminar at CERN, Klaus von Klitzing, the 1985 Physics Nobel Laureate, explained how the definition of the kilogram will be revolutionised
