Theoretical investigation of a Ni-like xenon X-ray laser in the 13–14 nm range

Several efficient laser transitions in Ni-like xenon in the 13 – 14-nm range are predicted on the basis of atomic kinetic calculations of the gains. The time characteristics of the gain g(τ) as functions of the electron density, temperature, and the diameter of the plasma column are considered. The results of calculations can be used to optimise the pump parameters with the aim of maximising the gain.
