Abstract

Since its first experimental successes more than a decade ago, plasma wakefield acceleration has in recent years drawn more and more interest in the accelerator community, as significant performance improvements and technological milestones were achieved. Taking advantage of the extremely strong wakefields inside a plasma accelerator, these machines can accelerate electron beams created through internal injection or injected externally from another machine to hundreds of MeV up to several GeV over mm- to cm-lengths. With such a reduction in accelerating distance by up to three orders of magnitude compared to radiofrequency (RF)-based devices, plasma technology is very promising for miniaturizing accelerator-based machines, such as light sources, thus potentially opening up a multitude of new applications and fields of use. To advance the development of plasma accelerators towards applications and user readiness, the EuPRAXIA project aims to tackle some of the field's most challenging technical and operational issues, including beam quality, machine reliability and operability as well as the currently very low repetition rate of plasma-based devices. With a team of 41 partners from 14 countries (as of November 2018), the project aims to develop a first plasma-acceleratorbased user facility. It is foreseen as a distributed European demonstrator and Open Innovation platform dedicated to the research and development of accelerator concepts and applications of plasma wakefield acceleration. This paper provides a short summary of the general status of the project as well as the current considerations for the future EuPRAXIA infrastructure.
