High repetition rate laser systems: targets, diagnostics and radiation protection Available to Purchase

Accessing the high repetition regime of ultra intense laser‐target interactions at small or moderate laser energies is now possible at a large number of facilities worldwide. New projects such as HiPER and ELI promise to extend this regime to the high energy realm at the multi‐kJ level. This opportunity raises several issues on how best to approach this new regime of operation in a safe and efficient way. At the same time, a new class of experiments or a new generation of secondary sources of particles and radiation may become accessible, provided that target fabrication and diagnostics are capable of handling this rep‐rated regime. In this paper, we explore this scenario and analyse existing and perspective techniques that promise to address some of the above issues.
