Science and Technology Offer at the ELI Beamlines Facility

 The ELI Beamlines Facility is a pillar of the ELI (Extreme Light Infrastructure) ERIC pan-European Research Infrastructure hosting the world’s most intense laser sources. ELI Beamlines developed and operates four cutting edge high-peak, high-average power femtosecond laser systems and offers a unique combination of primary (lasers) and secondary (high-energy particles and X-rays) sources to the international user community. Currently, several beamlines are operational and being upgraded to reach their full performances, while other beamlines are in their commissioning phase.

Laser-driven particle accelerators have gained interest in recent years thanks to their versatility and innovative features. This interest has pushed forward the development of beamlines where users can exploit the unique parameters (e.g. ultrashort bunch duration and ultrahigh dose rate) of laser-driven particle accelerators (ion and electron beams) and radiation (XUV to $\gamma$-ray sources) for a wide range of applications.

The current performance of particle and radiation sources available at the ELI Beamlines user facility will be presented and discussed along with their use for multidisciplinary applications. The combination of optical, X-ray, and particle beams for user experiments related to inertial confinement fusion and shock physics will also be presented in relation to the availability of a unique kJ-class, nanosecond laser beam operating at unprecedented repetition rate (~1 shot/min). The high repetition rate capability of the available primary and secondary sources will be highlighted in combination with a range of advanced target delivery solutions and diagnostics in operation in extreme laser-plasma conditions (>10$^{21}$ W/cm$^{2}$ at >1 Hz).
