From beam dumps to missing energy: the SPS search for hidden particles
For more than four decades, CERN’s Super Proton Synchrotron has served as a testing ground for new ways to search for particles that interact only feebly with ordinary matter. In a recent lecture, NA64 co-spokesperson Paolo Crivelli traced the evolution of this programme – from the first beam-dump experiments to missing-energy and missing-momentum searches, precision…

The last beam tests before LS3 boost FCC-ee detector technologies
The last beam tests before LS3 boost FCC-ee detector technologies by Hector Garcia Morales (CERN, EPFL) In one of the last opportunities to test detector prototypes before CERN’s accelerator complex enters Long Shutdown 3, a beam test campaign brought together different teams from across the world to test FCC-ee detector technologies. To date, six different

Investigating the origin of elements with the Alpha Magnetic Spectrometer on the international Space Station
Drawing on 15 years of observations and more than 260 billion cosmic-ray events, the Alpha Magnetic Spectrometer is helping scientists investigate how elements are produced and propagate through our Galaxy. Its latest measurements of phosphorus, chlorine, argon, potassium and calcium reveal distinct patterns among primary and secondary cosmic-ray nuclei, contributing to a more comprehensive model…

Designing for the unusual: LLP2026 and the lifetime frontier
LLP2026 brought around 80 theorists and experimentalists to Cambridge at a moment of transition for the lifetime frontier. From new searches using Run 3 LHC data and unconventional signatures to prototype detectors and new experimental concepts, the workshop showed how long-recognised blind spots are being turned into concrete experimental capabilities.

The ISOLDE Improvement Programme
The ISOLDE Improvement Programme The ISOLDE Improvement Programme (IIP) brings together a series of upgrades and consolidation activities to maintain and further develop the ISOLDE facility. The programme includes projects addressing the accelerator infrastructure, beam production, and delivery systems, and experimental facilities, with the objective of improving operational flexibility, reliability, and long-term sustainability. Among the

Accelerating Argon Ions at the SPS
Accelerating Argon Ions at the SPS This year, the SPS accelerated argon ions for the first time, delivering beam to the NA61/SHINE experiment in the North Area. NA61/SHINE explores the phenomenon of deconfinement by studying the collisions of ions of different masses, at different energies. As argon ions are much lighter than lead ions that
