# Numerical Simulation of Back Discharge: Influence of Pinhole Geometry on the Regime Transitions

Abstract : This paper presents numerical simulation of back discharge activity that is modelled at a pinhole in a dielectric layer on plane anode. First, for a given pinhole geometry, the transitions between back discharge regimes have been depicted as a mode diagram. Then, we have studied the influence of the dielectric layer thickness on the regime transitions. We have shown that increase in the layer thickness (within range of 0.02\textendash0.2 mm) promotes the back discharge development. Finally, we have studied the influence of crater configuration'. We have shown that crater shape' favours the back discharge ignition, whereas limits the resulting discharge development.
