The LUNEX5 project: planning future generations of light sources
LUNEX5 (free electron Laser Using a New accelerator for the Exploitation of X-ray radiation of 5th generation), a new advanced Free-Electron Laser (FEL) project proposed by a consortium of laboratories in France, aims at investigating the production of ultra-short (fs), intense, and coherent pulses in the soft X-ray region (20 - 4 nm).
LUNEX5 (free electron Laser Using a New accelerator for the Exploitation of X-ray radiation of 5th generation), a new advanced Free-Electron Laser (FEL) project proposed by a consortium of laboratories in France, aims at investigating the production of ultra-short (fs), intense, and coherent pulses in the soft X-ray region (20 - 4 nm). It consists of a single FEL line designed for the seeded configuration (high order harmonic in gas seeding and echo enabled harmonic generation) including in-vacuum undulators with two accelerators: a 400 MeV linac or a 0.4-1 GeV laser wake field accelerator, and experimental stations for time-resolved pilot user experiments on gas phase species and magnetic samples. After completion of the conceptual design report followed by a project review, complementary studies to be coupled to further R&D activities have been started.
