Using a static mass-spectrometer we studied the effect of the target irradiation with neutrons on the parameters of the plasma particles generated from such irradiated targets under the action of laser radiation. We found that the defects in the crystal structure of targets, due to the irradiation, influence not only on the efficiency of the material evaporation process and emission of the plasma, but also on the efficiency of ionization and recombination processes, which takes place in the plasma bunch on the stage of formation and expansion.
In this work we discuss three methods to improve characteristics of laser source of ions, namely: i) effect of the angle of interaction of laser radiation with targets on the plasma ions characteristics, ii) the use of targets of different densities to improve the parameters of plasma ions, and iii) influence of laser frequency on the plasma parameters. Our study will be based on the analysis of mass-charge spectrum of laser-produced plasma ions for different intensity of laser radiation.
