The Target Normal Sheath Acceleration method was employed at PALS to accelerate ions from laser-generated plasma at intensities above 1015 W/cm(2). Laser parameters, irradiation conditions, and target geometry and composition control the plasma properties and the electric field driving the ion acceleration. Cu nanoparticles deposited on the polymer promote resonant absorption effects, increasing the plasma electron density and enhancing the proton acceleration. Protons can be accelerated in the forward direction at kinetic energies up to about 3.5MeV. The optimal target thickness, the maximum acceleration energy and the angular distribution of the emitted particles were measured using ion collectors, an X-ray CCD streak camera, SiC detectors and a Thomson Parabola Spectrometer.
