PLASMA JET EMITTER: SIMULATION MODEL FOR THE PLASMA IN A SMALL ION SOURCE

摘要

A program that simulates a small ion source plasma in the cylindrical coordinate system is developed. In this computation, technique of Particle-in-Cell is used. The program includes the electromagnetic field of three dimensions, the process of the ionization by electron's collision, a discharge electric current and so on. Comparing the results of the calculation for ion source plasma using this program with experimental results for PIG ion source, we get good agreement for the electronic temperature, the electron and the ion density. As a result of this calculation, we will be able to analyze the plasma jet emitter that has cylindrical discharge tube with axial magnetic field by considering the collision mechanism and the examination of the initial condition.
