【 摘 要 】

Numerical model for the simulation of characteristics of Penning discharge is presented in the paper. The model is based on the 2D/3V axisymmetric electrostatic particle-in-cell algorithm implemented on unstructured triangular meshes. In order to simulate kinetic processes in the gas discharge plasma Monte-Carlo collision (MCC) method was incorporated into the model. Considered processes for the numerical experiments are elastic scattering of electrons on the neutral particles and ionization of neutral particles by electrons. Using this model various characteristics of Penning discharge such as anode and cathode currents, distribution of charged components in the discharge chamber have been calculated at various applied voltages and magnetic flux densities. The results of numerical experiments have been analyzed and discussed.
