EuPRAXIA

EuPRAXIA is a European initiative to develop a multi-disciplinary plasma-based particle accelerator research infrastructure linking institutions such as CERN, DESY, INFN, CEA, STFC, Max Planck Society, and Elettra. The project aims to consolidate expertise from projects like CLIC, XFEL, FLASH, ELI, and EuPRAXIA@SPARC_LAB to deliver compact, high-gradient accelerators for science and society. Consortium partners include national laboratories and universities associated with ITER, European XFEL, Facility for Antiproton and Ion Research, and ESS networks.

Overview

EuPRAXIA is conceived as a pan-European research infrastructure similar in collaborative intent to ESFRI, Horizon 2020, Horizon Europe, and initiatives like EuroCirCol. It seeks to bridge efforts seen in FAIR, ELI Beamlines, ISIS Neutron and Muon Source, MAX IV Laboratory, and SPring-8 by focusing on plasma wakefield acceleration technology pioneered in experiments at SLAC National Accelerator Laboratory, DESY Zeuthen, RAL, LBNL, and Oxford University laboratories. Key industrial and academic stakeholders include Siemens, Thales Group, Oxford Instruments, Thermo Fisher Scientific, University of Manchester, Imperial College London, Politecnico di Milano, TU Delft, EPFL, KU Leuven, University of Strathclyde, and University of Barcelona.

Scientific goals and research program

Scientific goals align with research agendas similar to those set by European Research Council, CERN Council, IUPAP, and funding frameworks like Marie Skłodowska-Curie Actions. The program targets compact sources for applications championed by ESRF, Diamond Light Source, Soleil, MAX IV, and APS communities, while addressing challenges explored at Princeton Plasma Physics Laboratory, Lawrence Berkeley National Laboratory, University of California, Los Angeles, University of Michigan, Columbia University, MIT, Stanford University, and Harvard University. Research themes include controlled beam quality inspired by XFEL Europa, high-repetition-rate drivers influenced by European XFEL operations, and integration with photon science seen at SwissFEL, FERMI, and Pohang Accelerator Laboratory.

Accelerator design and technology

Design concepts build on plasma wakefield acceleration demonstrations from FACET-II, AWAKE, BELLA Center, CLARA, and SPARC. Technology elements reference RF systems like those at CERN SPS, superconducting RF approaches from DESY Hamburg, cryogenics from Max Planck Institute for Solid State Research, laser systems analogous to ELI-NP and Vulcan Laser, and timing/synchronization systems used at XFEL. Components draw on magnet technology from BESSY II, diagnostics from Diamond Light Source, and control architectures inspired by EPICS implementations at Oak Ridge National Laboratory and Brookhaven National Laboratory.

Planned facilities and consortium sites

Planned hosting sites were proposed across Europe with expressions of interest from entities including INFN Frascati, STFC Daresbury Laboratory, DESY, Elettra Sincrotrone Trieste, CNR, CEA Saclay, IST Lisbon, TU München, CERN, RAL, University of Strathclyde, Politecnico di Milano, KU Leuven, Chalmers University of Technology, Uppsala University, Sincrotrone Trieste, SINAP, and regional centers like ELI-Beamlines. Site selection processes mirrored procedures used by ESFRI Roadmap and consultations with stakeholders such as European Commission, European Research Area, National Centre for Scientific Research (CNRS), and national ministries represented in GÉANT governance.

Collaborations and funding

The consortium model parallels collaborations like ITER Organization, CERN Council, European Spallation Source, SKA Organisation, and Horizon 2020 consortia. Funding lines draw on mechanisms used by European Commission, European Investment Bank, European Regional Development Fund, InnovFin, ESA, Euratom, and national research councils such as UK Research and Innovation, ANR, DFG, Italian Ministry of Education, Universities and Research, and Spanish Ministry of Science. Industrial partnerships reference procurement and IP models seen at Siemens AG, Thales Group, Canon, Zeiss, and Rutherford Appleton Laboratory spin-offs.

Applications and potential impact

Potential applications span photon science akin to X-ray Free-Electron Laser, medical therapies comparable to proton therapy at CNAO and GSI Helmholtz Centre for Heavy Ion Research, compact accelerators for materials analysis used at ISIS, industrial inspection workflows similar to Fraunhofer Society projects, security screening prototypes influenced by EURATOM safeguards, and accelerator-driven systems concepts examined in MYRRHA and IFMIF. Societal impact includes workforce development analogous to Marie Curie Fellows networks, technology transfer pathways like CERN Business Incubation Centre, and innovation clusters similar to Silicon Saxony and Medicon Valley.

Timeline and milestones

Milestones were planned following project phases comparable to ESFRI proposals: conceptual design, technical design, prototyping, and commissioning as practiced by European XFEL, ESS, ITER, and SKA. Early deliverables referenced demonstration goals from AWAKE Run 1, FACET, and BELLA experiments, with target dates aligning with EU funding cycles Horizon 2020 and Horizon Europe program periods. Consortium reporting and review structures leveraged models used by European Research Infrastructure Consortium and evaluation frameworks from ERC panels.
