Numerical matching an EUV laser of recombination tipe on hydrogen-like ions of nitrogen with a pulse energy supply system

Results of the numerical study of problems in matching electrodischarge EUV lasers on hydrogen-like ions of nitrogen (¿=13.4 nm) with pulse energy supply systems consisting a generator of high-voltage pulses and a transmitting line are reported. The length of the transmitting line was chosen such that the waves reflected from capillary loads could not influence on processes occurring in loads. The load itself represents a ceramic tube with close geometry of electrodes. The carried out numerical experiments have shown, that effective input of energy in the load occurs when the sum of ohmic and dynamic components of the discharge resistance approximately equals the wave resistance of the transporting line. In this case, the wave reflected from the load, carries away minimal energy. In the given type of lasers for heating of plasma columns and in the further for radiation cooling of electrons, collapsing shock waves are used. Therefore, the optimization should be carried out with account of interaction of shock waves with the current piston. Thus, it is possible to avoid an excessive removal of energy by reflected waves from the load and to minimize energy input into it for making effectively recombining active medium. It will help to realize short-wave EUV lasers with enough high life time of discharge tubes.
