摘要：

Pinching discharge in non-ablative and ablative capillaries filled by boron vapors is studied. The aim is to find out conditions for lasing at Balmer alpha transition of hydrogen-like boron ions B4+ (lambda= 26.23 nm). The primary pumping process under consideration is a three-body collisional recombination, which takes place in non-stationary underheated plasma during the pinch expansion stage. The results of Z-pinch computer modeling including the plasma kinetics and gain evaluation are compared for two different quarter periods of electrical current passing through the capillary.
