Job DescriptionThe Cooling & Ventilation (CV) Group is responsible for the design, installation, commissioning, operation, and maintenance of the cooling systems, pumping stations, air conditioning plants, and fluid distribution networks serving CERN's accelerator complex, experimental areas, selected LHC detector cooling systems, and strategic technical infrastructures such as the Computer Centre.This project aims to identify, evaluate, and implement solutions to improve the energy efficien

Sometime in March 1989, Mike Sendall — head of CERN’s computing and electronics group — read an eleven-page memo from one of his software engineers and wrote four words across the cover: “Vague, but exciting.” The memo, titled “Information Management: A Proposal” and dated 12 March 1989 , had been…

Researchers have used CERN’s Large Hadron Collider to model how high-energy cosmic rays enter the Earth’s atmosphere. The Northern Lights, which occur when particles from the Sun enter the Earth’s atmosphere, generate brilliant sky displays in our Northern Hemisphere, offering an occasional cosmic show enjoyed by millions. But how collisions between these particles, or low-energy cosmic rays, and the Earth’s gases result in the Northern Lights are less well-understood. Even more puzzling are collisions involving high-energy cosmic rays, which possess more than one million times the energy than those from the Sun and emanate from exploding stars, or supernovae. Scientists have typically relied on computer simulations to unpack their collision with Earth’s atmosphere, but these methods have produced varied, and sometimes conflicting, results. New research by an international team of physicists takes an unprecedented approach that offers a clearer understanding of these interstellar wonders. Using CERN’s Large Hadron Collider, the scientists have recreated how high-energy cosmic rays enter the Earth’s atmosphere and collide with our planet’s gases. The results in the journal Physical Review Letters help decipher the origins of interstellar particles from the cosmos. “We now have a better understanding of how particles from objects more exotic than the...

The European Laboratory for Particle Physics, usually just called CERN, is not only the birthplace of the World Wide Web, it is home to the Large Hadron Collider (LHC), the world's largest and highest-energy particle accelerator. As such, its computing environment is both truly unique and of great interest to people outside of CERN who hope to find lessons applicable to their own computing needs. The upcoming migration of some of CERN's systems from CentOS Linux to Debian, which was the topic of a talk at the recent MiniDebConf Winterthur 2026, is of particular interest.

Particles left behind by decaying Z bosons reveal strong evidence of quantum entanglement at CERN’s Large Hadron Collider. Z bosons, heavy elementary particles that decay almost as soon as they form, leave behind clues to a connection that can outlast physical separation. Known as quantum entanglement, this connection links particles’ quantum properties so that measuring [...]
