| সংক্ষিপ্ত: | Title screen The results of the simulation and experimental study of the high-power ion beam generation in an ion diode with a passive anode (accelerating voltage of 250-300 kV, pulse duration of 150 ns, beam energy per pulse of ≈50 J) are presented. The studies were carried out on a diode with a stainless steel anode during operation in the mode of double pulses of different polarities and plasma formation at explosive emission of electrons during the first pulse. It is found that a diode with a metal anode generates nitrogen ions, and the content of heavier ions of the anode material (Fe+) is insignificant. It is shown that the suppression of the heavy ion generation in an ion diode with a passive anode is caused by a higher expansion rate of the light-ion component of the anode plasma. The penetration depth of the electric field into the anode plasma is less than the layer thickness of lighter ions at its emission boundary; therefore, only light ions are emitted from the anode plasma and accelerated in the anode-cathode gap. The suppression of the heavy ion generation in a diode with a passive anode is a positive effect that provides an increase in the ion current when operating in the current limitation mode by the volume charge and a decrease in the density of impurity ions.
