Modelling of Capillary Z-Pinch Recombination Pumping of Hydrogen-Like Ion EUV Lasers

We report here new results of simulations of Z-pinch recombination pumping for capillary filled by boron and compare them with previous nitrogen results. In both cases the same capillary radius and current pulse shape are taken into account. Evaluated pressure optimized gains for boron and nitrogen are 1.04 cm−1 and 0.11 cm−1, respectively. Influence of possible wall ablation is also analyzed.
