Abstract
Using the PALS iodine laser system, Au ions with the charge state up to 58+ and with the kinetic energy as high as ~300 MeV were generated. The production of these ions was tested in dependence on the laser frequency (1, 3), on the irradiation/detection angles (0, 30), on the focus position with regard to the target surface, and on the target thickness (500m, 200m, 80m). A larger amount of the fastest ions was produced with 1 than with 3, the most of the fast ions were recorded in the direction ~10 from the target normal, the optimum focus position is in front of the target and should be set on with a precision of 50m. The forward emission is weaker than the backward one for both of the thinner targets (which burn through) at our experimental conditions.
