TL;DR: The EuPRAXIA project aims at the construction of an innovative electron accelerator using laser-and electron-beam-driven plasma wakefield acceleration that offers a significant reduction in size and possible savings in cost over current state-of-the-art radiofrequency-based accelerators as discussed by the authors.

TL;DR: In this paper, the beam longitudinal and transverse phase-space of the presently available LWFA beams are manipulated using variable strength quadrupoles, and the useful energy range passing through a slit in a magnetic chicane is selected.

TL;DR: In this article, an innovative electron beam longitudinal and transverse manipulation in the transport towards an undulator is proposed, where a "demixing" chicane sorts the electrons according to their energy and reduces the spread from 1% to one slice of a few.

TL;DR: In this paper, the authors describe the development of a full scale (2 m), 18 mm period Pr2Fe14B cryogenic permanent magnet undulator (U18), which is used to produce hard X-rays on synchrotron radiation based storage ring facilities of intermediate energy and enable short wavelength Free Electron Laser.

TL;DR: The QUAPEVA as discussed by the authors is a permanent magnet based quadrupole, composed of a Halbach ring and surrounded by four permanent magnet cylinders, which can reach up to 200 T/m for a typical 10 mm bore diameter.
