EPAC is a new user facility at STFC, in the UK, due to come online in 2025.




EPAC is a new national ​facility to support UK science, technology, innovation and industry.

The building construction phase of EPAC was completed in May 2022 and the building has been handed over to the CLF, ready to begin work installing and commissioning the systems needed to operate the facility from it​s ​expect​ed opening in 2025. 

A partnership between UKRI, MoD, academia and industry; EPAC will bring together world-leading interdisciplinary expertise to develop and apply novel, laser based, non-conventional accelerators ​and particle sources which have unique properties. We expect this to produce scientific breakthroughs and stimulate new solutions to challenging problems to help advance UK scie​nce and technology, helping to keep us safer, improve our healthcare and support a cleaner, more productive economy.​​​

Project Timeline

EPAC is currently under development. Construction was completed in early 2022 and the building has been handed over to CLF teams to begin the complex installation of the new laser systems.
