Au49+, Pb50+, and Ta48+ ions from laser-produced plasmas

Abstract
Results of generation of intense currents of highly charged ions of heavy elements from laser‐produced Au, Pb, and Ta plasmas are reported. High‐power iodine laser PERUN operating with λ=1.315 μm was used for that purpose. Using a parabolic mirror with a hole in the center instead of a focusing lens increased the efficiency of the illumination system and made the ion measurements along the target normal possible. Multiply charged ions were recorded with an ion energy analyzer in a distance of 240 cm.
