Abstract
In the study numerical simulation of electrodynamic structure of Penning gas discharge formed in large volume discharge chamber with annular anode is performed. For numerical modelling computer code implementing two dimensional axisymmetric electrostatic particle-in-cell method on unstructured grids is used. Computer simulation results of the Penning gas discharge in He under pressure 3·10−4 - 9·10−4 mbar, anode voltage 1-2 kV in the presence of external magnetic field B∼0.1 T are provided. Comparison of numerical and experimental results is performed.
