TL;DR: In this article, an ultrashort pulse laser acceleration of protons that yields unprecedented maximum proton energies of 17MeV at a table-top Ti:sapphire laser power level of 100TW was investigated.

TL;DR: This experiment demonstrates the simultaneous availability of all the components indispensable for systematic radiobiological studies: a laser-plasma accelerator providing proton spectra with maximum energy exceeding 15MeV and applicable doses of a few Gy within a few minutes; a beam transport and filtering system; and an in-air irradiation site.

TL;DR: It is demonstrated in laser plasma wakefield electron acceleration that the beam loading effect can be employed to improve beam quality by controlling the beam charge and the final energy spread is minimized.

TL;DR: When transverse refluxing takes places within the acceleration time of associated ions, the coupling of ultraintense lasers with solid foils with limited transverse extent is analyzed, resulting in increased maximum proton energies, increased laser-to-ion conversion efficiency, and reduced divergence.

TL;DR: In this paper, the authors report on target needs for three different classes of experiments: dynamic compression physics, electron transport and isochoric heating, and laser-driven particle and radiation sources.
