摘要
A one-dimensional hybrid model of the dynamics of atoms, ions, and electrons in the channel of a stationary plasma thruster is developed. The relevant set of integrodifferential equations is studied numerically. The results obtained are compared with the results of previous calculations based on a hydrodynamic model. It is shown that, with the use of one fitting parameter (the channel resistance), the calculated integral characteris-tics agree well with the experimental ones. The current-voltage characteristic is obtained. The general features of low-frequency oscillations that have been revealed in numerical simulations using the model proposed are also in fairly good agreement with experimental results. The value of the electron thermal conductivity is estimated.
