Q1. What does the creation of the CIO role mean for CERN? CERN’s digital landscape is expanding continuously, with new tools, new capabilities and new ideas. In this context, CERN has established the ...

Computing power is the often invisible engine that enables research. As the Large Hadron Collider (LHC) is upgraded to deliver a dramatic increase in the number of particle collisions, the data ...

From Monday 6 July 2026, a new process will make it easier and more secure to submit your absence certificates. This change gives you clearer guidance on the conditions for each type of absence and ...

The Non-Collider Physics Roadmap aims to maximise scientific impact through a balanced assessment of physics opportunities, resources, feasibility, timelines, and community priorities, providing a ...

There’s more to CERN than the Large Hadron Collider. A series of accelerators work together to push particles to nearly the speed of light The accelerator complex at CERN is a succession of machines ...

From performing detailed studies of the Higgs boson to demonstrating the first antimatter quantum bit and converting lead nuclei into gold nuclei, this year CERN further expanded our knowledge of the ...

Cosmic rays are high-energy particles from outer space that strike Earth’s atmosphere, generating showers of secondary particles, such as muons, that can reach the planet’s surface. In recent years, ...

Following consultations conducted in close coordination with the Swiss and French authorities, extended opening hours and exceptional conditions for Gate E and the ...
