High-energy ions from a Nd-laser-produced plasma

Abstract

Measurements of the asymptotic energy distribution of the different high-energy ion species at Nd-laser irradiance 1015–1016 W/cm2 on a CH2 planar target are presented and the acceleration mechanism of these high-energy ions is discussed. Multipeak structure between 10 and 100 keV is observed on the H+ ion distribution. A disproportionate number of H+ ions with E/Z higher than the C+z ions is also observed.
