Computer model for electrode plasma generation by electron and ion flows

A model is proposed for computer simulation of the electrode plasma generation by electron and ion flows. The distribution of the absorbed energy of particles in the electrode material is calculated by the Monte-Carlo codes. This provides a possibility to control the electrode temperature by solving the heat conductivity equation for specified distributions of thermal sources and to calculate the rate of plasma generation. The behavior of the plasma in the gap can be modeled based on simple model where the velocity, the density, and the temperature of the plasma can be given by some dependence. Within the framework of the model proposed, numerical study is performed on the effect of the plasma flows in Rod Pinch Diodes and in the Insulator Stack of the Z-accelerator.
