The starting point of a particle’s journey 📍

to 1974 at the pre-injector of Linear accelerator 1 (Linac1), where protons began their journey towards the Proton Synchrotron (PS).

This high-voltage equipment, housed inside a large Faraday cage, gave the protons their first boost of energy. The cover over its high-voltage platform could be lifted for easy access when the accelerator was switched off.

: Linac1 was the only supplier of protons to the CERN synchrotrons until 1978, when Linac 2 took over.

The impact of CERN technologies: from fundamental research to our everyday lives 💫

CERN’s fundamental research and unique environment are fertile ground for innovations in particle accelerators, detectors and computing that can benefit society as a whole, sometimes in surprising ways.

: a public exhibition on CERN’s main site showcases in images some of the practical applications of CERN technologies and the expertise of CERN scientists and engineers.

If you’re in the region, the exhibition will be on display on the Esplanade des Particules until February 2027.

Five decades of collaboration, innovation, & groundbreaking achievements 🥳

This features the 50th anniversary of the Super Proton Synchrotron (SPS) – CERN’s second-largest accelerator – celebrated at CERN earlier this month, in the Globe of Science and Innovation.

From its first circulating proton beam in 1976 to the discovery of the W and Z bosons and its role today as the final injector for the , the SPS has continually reinvented itself.

Introducing: The Hybrid Nexus – 19 & 20 November 2026, CERN Science Gateway

Presented by Arts at CERN, the CERN Art and Science summit returns for its third iteration, The Hybrid Nexus. This gathering will explore the convergence of particle physics, quantum technologies, and artificial intelligence, and the ways in which these fields extend into contemporary creation and thought.

The Hybrid Nexus brings together leading voices from science, philosophy, culture, and the arts to reflect on the new horizons emerging from this convergence, examining the “boundary regions of science” that offer “the richest opportunity to the qualified investigator” [Norbert Wiener, 1948].

Day 1 | Thursday, November 19, 18:00 – 20:30:

The evening event features theoretical physicist Sabrina Pasterski; art critic, philosopher, and curator Daniel Birnbaum; curator, art theorist, and educator Marta Kuzma; artists Wendi Yan and Robin Meier Wiratunga; and CERN scientist and researcher Sofia Vallecorsa.

Day 2 | Friday, November 20, 10:00 – 18:30:

The full-day event features research and design studio Metahaven; Declan Colquitt, Project Lead at MOTH Quantum; artists Rosa Barba, Dominique Koch, Martyna Marciniak, and Amanda E. Metzger; curators Marta Kuzma, Lívia Nolasco-Rózsás and Enrique Rivera Gallardo, and scientist Puneet Anantha Murthy.

Can you guess what this is?
Hint: It’s right at the heart of particle collisions. ❤️

Here we see the extraction of the Forward Pixel (FPix) Tracker from the CMS Experiment at CERN detector in September 2026, in preparation for the .

The Pixel Tracker is the sub-detector closest to the beam pipe and the interaction point (IP), where the two proton beams circulate in the Large Hadron Collider ( ).

The will produce many more particle collisions, increasing the demands on the CMS detector. Upgrading the tracking system will help it maintain precise particle tracking in these more challenging conditions.

: The Pixel Tracker is made of concentric layers and rings of more than 1800 small silicon modules.

Particle collisions – episode 2 💫

In the previous episode of this three-part series, named “Particle collisions”, we talked about particle collisions in an accelerator, and we saw how fundamentally random they are.

At the , is it is impossible to know what the next collision will produce. How can physicists predict how many , Z bosons or other particles to expect in an experiment?

In the second episode of Particle Collisions, we explore luminosity and cross-section, how they connect an accelerator to the physics it produces, and why particle physicists measure data in "inverse femtobarns".

CERN and Mistral join forces to accelerate AI for science 💫

CERN, and Mistral, a European developer of large-scale models, have signed a statement of intent to establish a long-term strategic partnership focused on developing foundation models for scientific discovery.

One of them is intended to address a fundamental challenge in analysing collisions.

A spin through CERN’s history 💫

to 1973, when the first of two rotary condensers for the radio-frequency system of CERN’s Synchrocyclotron (SC) – the Laboratory’s first accelerator – arrived .

The condenser produces the frequency required to accelerate particles. Here, the team is checking the gaps between the rotating blades and the stationary blades.

The first condenser was transported to CERN in June 1973, while a second, spare one was being completed in Berlin.

Studying beautiful flavour transitions ✨

CMS Experiment at CERN and LHCb Experiment at CERN researchers have released their latest results on the rare transformation of a beauty quark into a strange quark and two muons.

The illustration shows the transformation of a bottom quark into a strange quark, a muon and an antimuon (b→sμ+μ-) via the weak interaction.
