The laser irradiation of TiH2 targets has been investigated to measure the proton energy transferred by hot non-equilibrium plasmas in vacuum. The proton and titanium emission have been monitored by time-of-flight measurements to evaluate their maximum ion energy and dependence on the laser intensity. Backward and forward plasma have been generated in the range 10(10)-10(16) W/cm(2) intensity using ns and sub-ns laser shots. Proton energy has been measured by tens eV up to about 4 MeV. The interest in proton beams generated by laser-plasma is presented and discussed.

Abstract

The laser irradiation of TiH2 targets has been investigated to measure the proton energy transferred by hot non-equilibrium plasmas in vacuum. The proton and titanium emission have been monitored by time-of-flight measurements to evaluate their maximum ion energy and dependence on the laser intensity. Backward and forward plasma have been generated in the range 10(10)-10(16) W/cm(2) intensity using ns and sub-ns laser shots. Proton energy has been measured by tens eV up to about 4 MeV. The interest in proton beams generated by laser-plasma is presented and discussed.
