2D simulation of snowplow model for microsecondconductiontime lasma opening switch

A general understanding of the microsecondconductiontime plasma opening switch in the conduction and opening phase is summarized. The snowplow model including the equations and its differential formation is described. A result with inner radius of 5 cm and outer radius of 7 cm is given. The POS conduction time is predicted to be 1 005ns. Also the simulation result points out that the phase of plasma thinning appears at radius of 5.75 cm.
