The scientists represent expertise from accelerator science and high-energy 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. A project with 14 work packages has been defined, 8 of them funded by the EU. 

EuPRAXIA brings together a consortium of 16 laboratories and universities from 5 EU member states. As of October 2016, 22 associated partners from 11 countries have joined with in-kind commitments (linking 3 additional EU member states).

The EuPRAXIA study involves scientists working on accelerators, high-power lasers, free-electron lasers and high-energy physics. Moreover, research and development on electron plasma acceleration is carried out in multiple institutions scattered around Europe, Asia and the United States.
