TL;DR: In this paper, the authors extend the energy and intensity range over which proton scaling is experimentally investigated, up to 400 J and 6×10^20 Wcm−2 respectively, and find a slower proton scale than previously predicted.

TL;DR: A hybrid acceleration scheme based on the relativistic induced transparency mechanism using linearly polarised laser interaction with foil targets is demonstrated and its future implication in using high power lasers is explored.

TL;DR: The developments in this research field are reviewed and the potential of laserproduced proton, neutron, and heavy ion beams, together with isotope and isomer production is described.

TL;DR: In this article, the authors measured an energy loss in the postcollision electron spectrum that is correlated with the detected signal of hard photons (gamma rays), consistent with a quantum description of radiation reaction.

TL;DR: The spectral features provide evidence of a multispecies scenario of radiation pressure acceleration in the light sail mode and indicates that monoenergetic peaks with more than 100 MeV/nucleon are obtainable with moderate improvements of the target and laser characteristics, which are within reach of ongoing technical developments.
