World’s first crabbing of a proton beam

CERN has successfully tested “crab cavities” to rotate a beam of protons – a world first. The test took place on 23 May using a beam from CERN’s Super Proton Synchrotron (SPS) accelerator and showed that bunches of protons could be tilted using these superconducting transverse radiofrequency cavities. These cavities are a key component of the High-Luminosity Large Hadron Collider (HL-LHC), the future upgrade of the LHC.

A new era of precision for antimatter research

 

The ALPHA collaboration has reported the most precise direct measurement of antimatter ever made, revealing the spectral structure of the antihydrogen atom in unprecedented colour. The result, published today in Nature, is the culmination of three decades of research and development at CERN, and opens a completely new era of high-precision tests between matter and antimatter.

Arts at CERN announces the winners of the Collide residency awards

Arts at CERN pioneers new ways of bringing together artists and scientists, leads the conversation about art and science, and supports artistic creativity and curiosity towards fundamental research. Artists from all over the world are invited, through our cultural programmes, to spend time at CERN and work alongside particle physicists and engineers.

First high-precision measurement of the mass of the W boson at the LHC

Geneva 12 February 2018. In a paper published today in the European Physical Journal C, the ATLAS Collaboration reports the first high-precision measurement at the Large Hadron Collider (LHC) of the mass of the W boson. This is one of two elementary particles that mediate the weak interaction – one of the forces that govern the behaviour of matter in our universe. The reported result gives a value of 80370±19 MeV for the W mass, which is consistent with the expectation from the Standard Model of Particle Physics, the theory that describes known particles and their interactions.
