The Particle Physics Department
The Particle Physics Department (PPD) at STFC drives world-class experiments that probe the fundamental structure of matter and the forces that shape our Universe. By designing and operating cutting-edge detectors, accelerators, and data-analysis tools, PPD supports the UK particle physics community and collaborates internationally to deliver discoveries that expand knowledge, inspire innovation, and create lasting scientific and societal impact.
What makes us unique
PPD combines world-leading expertise, national facilities, and global partnerships to tackle the deepest questions in physics.
From designing and building advanced detectors to operating large-scale experiments at RAL, CERN, and beyond, PPD offers the UK particle physics community unrivalled access to cutting-edge technology, data, and scientific collaboration, turning bold ideas into discoveries that shape our understanding of the Universe.

Partnering with CERN
PPD collaborates closely with CERN, home of the Large Hadron Collider, to design, build, and operate world-leading experiments. UK scientists at PPD contribute to the ATLAS, CMS, and LHCb experiments, helping to explore the fundamental constituents of matter and search for new physics.
