Design and optimization of a compact laser-driven proton beamline

Abstract Laser-accelerated protons, generated by irradiating a solid target with a short, energetic laser pulse at high intensity (I > 1018 W·cm −2), represent a complementary if not outperforming source compared to conventional accelerators, due to their intrinsic features, such as high beam c...
