EuPRAXIA is a distributed, compact and innovative accelerator facility based on plasma technology. In its first phase, its consortium of 51 institutes and industry partners will construct an electron-beam-driven plasma accelerator in the metropolitan area of Rome. In its second phase, EuPRAXIA will build one laser-driven plasma accelerator at a site to be chosen between several options in Europe. EuPRAXIA will serve users in ultra-fast science, e.g. on high-resolution medical imaging, deeply penetrating positron annihilation spectroscopy for materials and with Europe’s most southern free-electron laser (FEL). It will offer fascinating capabilities for research on biomolecules, viruses and microscopic processes. EuPRAXIA will thus be a transformative step in the development of ultra-compact accelerators and applications. The EuPRAXIA RI will demonstrate an innovative electron accelerator based on plasma wakefield acceleration, with a beam energy of 1 to 5 GeV and a beam quality equivalent to present radiofrequency (RF) linear accelerators, and demonstrated benefits in size and cost. EuPRAXIA will implement this strategic vision by streamlining and integrating the efforts of accelerator, plasma and laser research communities, in association with European industry, to bring plasma accelerators to the users and the market. A key short-term impact of EuPRAXIA lies in the collaboration of its 51 organisations, institutes and industry partners. It proposes a model for the construction of plasma accelerators in a fair and distributed open innovation approach beneficial to consortium partners, industry, and researchers. Major technical innovation will be furthered in plasma accelerating stages, RF technology, ultra-fast synchronisation and electronics, the development of compact, high-field quality accelerator magnets, high-repetition-rate, petawatt-scale laser systems, as well as in fast detector technology for photon science and high-energy physics. Europe’s position in plasma accelerators, high-power lasers and compact applications will be further strengthened in the context of an intense international competition. In the medium term, the EuPRAXIA energy range and performance goals will enable versatile applications in various domains, including a compact FEL, compact sources for medical imaging and positrons, tabletop test beams for particle detectors, and highly mobile but deeply penetrating X-ray and gamma-ray sources for material testing. EuPRAXIA will increase the overall capacity for user experiments in photon and accelerator science in Europe, and will provide beam characteristics not available elsewhere, such as ultra-short radiation bursts, almost point-like emissions of X-rays with benefits in resolution and higher-energy positrons from an ultra-compact source. In the long term, the progress towards ultra-compact and more cost-effective accelerators and applications, which is in EuPRAXIA’s core mission, will lower the entry barrier for accelerator-assisted research, allowing access to research groups and countries typically not making use of particle accelerators. In the long term, we envisage that a new generation of fully industrialized, highly compact particle accelerators is developed for wide usage in research centres, universities, hospitals and companies, complementing large-scale RF accelerator facilities.

The EuPRAXIA consortium with 16 members was formed in 2014 and submitted a conceptual design in 2019 (EU grant no. 653782). New ideas were published with one receiving the Touschek prize from the Accelerator Group of the European Physical Society. The next-phase EuPRAXIA consortium has grown to 40 members and 11 observers.Employing a strategy that prioritizes risk management and equilibrium, the initiative will undertake the meticulous development of a comprehensive model delineating the legal framework and accessibility provisions for EuPRAXIA. Simultaneously, a series of project clusters, predominantly rooted within established research institutions and universities, will be orchestrated to convene various collaborators. Their collective objective will be to finalize the intricate technical blueprint, ensuring a thorough and cohesive design. At existing infrastructures in Germany, France, UK, Czech Republic, Portugal and Switzerland several excellence centres (national and thematic nodes) will be set up for prototyping, tests and components production. The construction of an electron-driven plasma accelerator at Frascati close to Rome is mostly funded. Its design phase is at advanced stage. Its implementation is expected to start in 2026. The construction of a brand new building that will house the electron driven plasm accelerator should start in 2026. The executive design of the civil infrastructures are on the way and the main authorizations from local authorities have been formalized. The site of the laser-driven plasma accelerator has several options in Europe and will be decided in 2025 for start of operation by 2032. The selection of the laser driven plasma pillar is at advanced stage and it will be chosen based on objective criteria.
EuPRAXIA is now in the middle of the Preparatory Phase Project (Horizon Europe), while part of the implementation phase has started at the Beam Driven Pillar (INFN-LNF). At the moment for obvious reasons there is no service available for potential users. However a dedicated work package within the Preparatory Phase Project is elaborating a strategy for user access and services provided. The existing photon science research infrastructures in Europe serve a very broad scientific community of more than 30,000 researchers. EuPRAXIA will deliver, amongst other particle beams, bright pulses of free-electron laser light in a facility based on a new technology for the acceleration of the required electrons. It will have naturally ultra-short pulses (few femto-seconds) and capabilities of pump-probe experiments. In the operational phase EuPRAXIA will offer a wide range of services to a vast and diversified user base aiming at advancing scientific research across different disciplines (life science, material science and engineering, high energy physics). One of the primary services provided will be the access to FEL beamlines to conduct experiments, this includes also experimental support for designing, planning and conducting the experiments and eventually also data storage and processing. In a second phase additional beamlines will be added for example betatron radiation source and positron source. Beamtime to conduct experiments will be offered as a service. The access policy will be defined by a dedicated work-package within the Preparatory Phase Project and will be based on scientific excellence and relevance. Members of the collaboration will have a fast-track user access but the facility will be opened to all the community and also industries. Technical expertise, instrumentation development (both for user end station and for accelerator) will be offered as a service. In addition, EuPRAXIA facilities are meant to offer particle accelerator, plasma and laser community a state-of-the-art machines to further develop and test novel ideas in particle accelerator technology (for example diagnostics scheme and study on advanced plasma capillaries).

Collaboration with other research infrastructures is pivotal in optimizing resource utilization, leveraging expertise, and accelerating scientific advancement. EuPRAXIA, as a distributed research infrastructure, places significant emphasis on effective partnerships with other RIs and academic institutions. The EuPRAXIA collaboration convenes leading European RIs specializing in Plasma Accelerator, Laser Technology, and RF Accelerator, employing a bottom up approach. Our collaboration with other RIs is underpinned by shared objectives. Within the framework of the Preparatory Phase Project (funded by HE), a collaboration agreement has been signed, and now under amendment process for expansion to encompass new members. Additionally, Memorandums of Understanding (MoUs) will be drafted to formalize specific collaborations with select RIs on targeted scientific domains. Strengthening the EuPRAXIA collaboration entails joint engagement in grant applications for research project aimed at increase the technology readiness level of the EuPRAXIA initiative. Another important aspect is the cooperative efforts in training and educational initiatives, fostering a skilled workforce and facilitating knowledge exchange among infrastructures (as EuPRAXIA DN funded by HE).
