A robot is tested with a view to enhancing security on CERN’s sites
Since 22 July 2026, CERN’s Security Service has been testing an autonomous robot designed to reinforce security monitoring on the Meyrin and Prévessin sites. The two-wheeled mobile robot is equipped with 360° cameras, a thermal imaging camera and acoustic sensors. It travels at speeds of up to 5 km/h and can operate for about eight hours

Computer Security: One click to many
More senior colleagues might still recall the regular “clicking” campaigns that were intended to raise security awareness within the Organization among staff and users. With the roll-out of two-factor authentication, such campaigns were dropped. However, the world continues to turn and novel functionality and novel attack vectors try to circumvent our protections. And they have

Works at Gate B: closures and access changes on the CERN Meyrin site from August 2026
Works at Gate B will result in several periods of full and partial closure between August 2026 and March 2027. Traffic diversions and adjusted opening hours at other entrances to the Meyrin site will be introduced to ensure uninterrupted access to the site throughout the works. The works will be carried out in several phases.

Oxygen collisions at the LHC show new indications of extreme state of matter
One year on from the first-ever collisions of oxygen at the Large Hadron Collider (LHC), the main LHC Collaborations – ALICE, ATLAS, CMS and LHCb – have each reported signs of the state of matter known as quark–gluon plasma (QGP) originating from these collisions. QGP is a state of matter that forms under intense pressure

HiLumi LHC: new magnets reach full power
The test bench for the High-Luminosity LHC, the IT (Inner Triplet) String facility, has reached a major milestone. On 8 July, its new quadrupole magnets – known as the inner triplet magnets – successfully reached their nominal operating current of 16 230 amperes. Designed to focus the beams more tightly than ever before, thereby increasing the
