Au{sup 49+}, Pb{sup 50+}, and Ta{sup 48+} ions from laser-produced plasmas

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 {lambda}=1.315 {mu}m 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. {copyright} {ital 1996 American Institute of Physics.}
