Amplification on the plasma of He-like nitrogen ions created by an extended high-current Z-discharge

The report presents the results for numerical modeling of the active medium of short-wavelength radiation sources. The main interest was paid to transition 3-2 in He-like nitrogen ions. With the help of the developed level kinetics model and non-stationary one-dimensional two-temperature magneto-radiation-hydrodynamic code the inversions of ion level populations and amplification coefficients were calculated.
