Abstract: Experiments on ion acceleration by irradiation of ultra-thin diamond-likecarbon DLC foils, with thicknesses well below the skin depth, irradiated withlaser pulses of ultra-high contrast and linear polarization, are presented. Amaximum energy of 13MeV for protons and 71MeV for carbon ions is observed witha conversion efficiency of > 10%. Two-dimensional particle-in-cell PICsimulations reveal that the increase in ion energies can be attributed to adominantly collective rather than thermal motion of the foil electrons, whenthe target becomes transparent for the incident laser pulse.
