EuPRAXIA features on cover of Physics of Plasma

An important step forward for EuPRAXIA has been marked by the publication of the “Technical Status Report on Plasma Components and Systems in the Context of EuPRAXIA”.  The article features on the front page of the November issue of Physics of Plasmas. A result of work done as part of Work Package 10, Plasma Components and Systems, of the Preparatory Phase Project, the article was prepared by experts across the EuPRAXIA collaboration. Their work reviews the current state of the art in this field for both laser- and beam-driven plasma accelerators and discusses the main challenges for implementing them in future EuPRAXIA facilities. 

EuPRAXIA aims to construct two state-of-the-art research facilities based on plasma accelerator technology. The two facilities - one laser-driven, one beam-driven - are planned to produce electron beams with an energy in the range of 1-5 GeV and beam quality comparable to existing radiofrequency accelerators.

These beams could support applications such as compact free-electron lasers and advanced imaging for medical and industrial use.  Plasma components and systems are central for both future EuPRAXIA facilities, and their design, fabrication, and optimization present a complex challenge that brings together expertise in fluid dynamics, materials engineering, and plasma physics. 

Achieving precise control, diagnostics, and simulations of these systems is key to meeting EuPRAXIA’s goals, along with ensuring stable, high-repetition operation and seamless beamline integration. 

The authors note that while plasma accelerators have achieved remarkable milestones, such as GeV-scale beams and improving stability, several challenges remain. These include maintaining beam quality, ensuring component durability, and achieving reliable, high-repetition operation. Addressing these issues will be key as EuPRAXIA transitions from concept to construction in the coming years.
