1 Laser-driven X-ray sources: realization and future trends Patrick Audebert, Julien Gautier, Fabien Quéré, Rodrigo Lopez-Martens, Le Thi Thu Thuy, Philippe Martin, Hamed Merdji, Pascal Monot, Eduardo Oliva, David Ros, Antoine Rousse, Stéphane Sebban, Kim Ta Phuoc, Sophia Chen and Philippe Zeitoun

2 Panorama of available laser-driven X-ray sources E (ev) FERMI, FLASH LCLS, SACLA Å l (nm)

3 lly over time, a nuclear battery can be built. If it is instantaneously be used as a rocket propellant Why or X-ray an explosive. sources The idea of for generating ELI-Nuclear Physics? dates back to the late 1990s. ys amplification by the stimulated emission of radiation from nuclear me a reality as gasers. Lasers is an acronym standing for: light he stimulated emission of radiation. Whereas light as electromagnetic involves photons with energies in the electron volts (ev) energy s with a higher frequency and a shorter wave length would carry llion electron volts (MeV) range.

4 The French teams at a glance CILEX is situated in the scientific environment of : 1) French research projects: ANR I-nano-X ANR FEMTO-X-MAG ANR COKKER and ROLEX ANR ASOURIX IRAMIS ISMO LOA LASERIX 2) French pre-industrial projects ASTRE ) European projects SFINX and INREX «Joint Research Activities» in LASERLAB2 and 3 LULI DAM LPGP LOA CELIA

5 X-rays within CILEX/APOLLON project X-rays may be either developed on short and long focal areas. Short focal area - allows performing most proposed experiments, - reduces the cost by sharing equipment Short focal area Apollon 10P Laser - and enables pumpprobe experiments in radio-protected area.
