Simulation of Electron Densities and Breakdown Voltages in Argon-Filled Cylindrical Electrodes

Breakdown voltage (VBD) is the most fundamental
parameter to detect different gases in ionization gas sensor.
In this work we present the simulated VBD in DC discharges
and combined DC and RF discharges in argon using
Particle-in-Cell Monte Carlo Collision (PIC-MCC) method.
Electron density which plays a crucial role in the
breakdown mechanism is also calculated at different
positions between the cylindrical electrodes. The breakdown
voltages agree well with experimentally measured and other
simulated data for various ranges of gas pressures.
