The European Plasma Research Accelerator with Excellence in Applications (EuPRAXIA) is a distributed, compact and innovative accelerator facility based on plasma technology. By using plasma wakefields gradients as high as some tens of billions of electron volts per meter – as much as 1,000 times more – EuPRAXIA will be a transformative step in the development of ultracompact accelerators that could be used for a wide range of fundamental and applied research applications. It is the important intermediate step between proof-of-principle experiments and ground-breaking, ultra-compact accelerators for photon science, structural biology, particle physics detector development, materials science, medical imaging, radiation therapy, protons sources for hadron therapy and industrial applications.
EuPRAXIA is the outcome of a consortium of 16 laboratories and universities from five European countries to prepare the Conceptual Design Report for the worldwide first high energy plasma-based accelerator. As of December 2020, the consortium has grown to 40 members and 11 observers. The scientific communities bring expertise from accelerator science and highenergy physics, design and construction of leading accelerators like the LHC, advanced acceleration test facilities like SPARC and frontier laser projects like CLF, CILEX-APOLLON and ELI. The construction of an electron-driven plasma accelerator in the metropolitan area of Rome is expected to be ready for operation in 2028. The site of the laser-driven plasma accelerator has several options in Europe aiming to start operation by 2032.
