SiC interdigit detectors for post-accelerated ions generated by laser plasma

The ion streams emitted from laser generated plasmas and post-accelerated through a high voltage acceleration path, were monitored by solid state 4H-SiC interdigit detectors in time-of-flight configuration. The plasmas are produced by irradiation of an aluminum target through a ns pulsed laser with 10(10) w/cm(2) intensity and 200 mJ pulse energy. Laser-generated plasma exhibits a mean energy of the order of 100 eV per amu. In order to enhance the ion kinetic energy a post acceleration in the range 1 kV -30 kV was employed.
