Abstract
In the Knudsen mode of a plasma diode, a dynamic potential barrier for ions can be formed during nonlinear oscillations occurring within the inter-electrode gap. We found that the barrier oscillations lead to the appearance of long-lived ions in the plasma. A simple model of the oscillating electric field is proposed, which allowed us to find out the reason for the appearance of such ions. The properties of long-lived ions, as well as a structure of the regions on the phase plane where these ions exist, are studied. The analytical results obtained using the model are in good agreement with the numerical simulation data. [ABSTRACT FROM AUTHOR]
