LUNEX 5 (free electron Laser Using a New accelerator for the Exploitation of X-ray radiation of 5th generation) aims at investigation the production of short intense and coherent pulses in the soft X-ray region with innovative schemes (such as echo and seeding with harmonics generated in gas) and compact design. The undulators of the FEL line are designed to provide high field short period devices: modulators are in-vacuum undulators with a period of 30 mm and 0.27 m long radiators are in cryo-ready vacuum undulators with period of 15 mm and 3 m long with a cryogenic option, relying on SOLEIL development experience of NdFeB U20 hybrid in-vacuum undulators and 2 m long PrFeB U18 cryogenic undulator operated at 77 K installed on a long straight section of SOLEIL. In addition, the line comports electromagnetic quadrupoles for the beam focusing; chicane dipoles for the beam compression and an electromagnetic bending magnet for the beam dump. A prototype of cryo-ready radiator is under design. Variable permanent magnet quadrupoles are under study for the transport of the Laser WakeField Accelerator towards the undulators.

LUNEX5 (free electron Laser Using a New accelerator for the Exploitation of X-ray radiation of 5th generation) aims at investigating the production of short, intense, and coherent pulses in the soft X-ray region (with two particular targeted wavelengths of 20 and 13 nm on the fundamental wavelength). The project consists of a Free Electron Laser (FEL) line enabling the most advanced seeding configurations (High order Harmonic in Gas seeding and Echo Enable Harmonic Generation) and in-vacuum (potentially cryogenic) undulators of 15 and 30 mm period. Two accelerator types feed this FEL line : a Conventional Linear Accelerator (CLA) with superconducting cavities of 400 MeV for the investigations of the advanced FEL schemes, compatible with a future up-grade for high repetition rate; and a 0.4 - 1 GeV Laser Wake Field Accelerator (LWFA), to be qualified in view of FEL application, in the single spike or seeded regime. Two pilot user experiments for time-resolved studies of isolated species and solid state matter dynamics will take benefit of LUNEX5 FEL radiation and provide feedback of the performance of the different schemes under real user conditions.
