The SPS turns 50
Protons, antiprotons, electrons, positrons, oxygen and lead ions… the Super Proton Synchrotron (SPS) has been juggling particles with ease for the past 50 years. By turns an accelerator, a collider and an injector, this versatile machine has seen generations of scientists pass through its doors, supplied dozens of experiments and given rise to groundbreaking technologies

Niels Doble (1938–2026)
Niels Doble (1938–2026) — Niels Doble, born on 2 May 1938, passed away on 8 August 2026 after a short illness. Niels was best known for his pivotal contributions to the initial design and subsequent operation of the North Area at the Super Proton Synchrotron (SPS) complex. Niels studied physics at the University of Bristol.

Accelerator Report: Beyond the LHC – CERN’s Beams Keep Science Moving
The Large Hadron Collider (LHC) may have entered Long Shutdown 3 (LS3), but across the rest of CERN’s accelerator complex operations remain as busy as ever. The LHC injector chain continues to provide proton beams for a broad range of users, including the ELENA antiproton community, the East and North Area experiments and the n_TOF

Crystal shadowing to reduce beam losses
A new system made of precisely aligned thin, bent crystal arrays will greatly improve particle beams sent to fixed-target experiments in CERN’s North Area, while also protecting sensitive equipment

Which bin should I use for my unwanted cast-iron blocks?
Got any blocks of cast iron lying around in a corner of your office? They might be useful for the future Beam Dump Facility (BDF) for the SPS

Accelerator Report: A summer of hot spells for the LHC
So far the summer run has seen solid progress in luminosity production, but also some unexpected beam and machine behaviour. Careful monitoring revealed a hardware issue, now being closely watched as the LHC continues to perform at full capacity.

Accelerator Report: The LHC wraps up its first 2025 physics block
The proton physics run has now been paused for the first block of machine development studies, a technical stop and short oxygen- and neon-ion physics runs. Protons will be back in the machines on 12 July
