We report systematic studies of laser-driven proton beams produced with micrometer-thick solid targets made of aluminum and plastic, respectively. Distinct effects of the target materials are found on the total charge, cutoff energy, and beam spot of

Particle emittance quantifies the ability to focus and transport a beam, and is one of the most important parameters for a beamline. The emittance of a proton beam produced by ultraintense laser irradiation of a micron-thick flat solid target has bee
