Paper Abstract

The optically triggered psuedo-spark, also known as the Back-Lit-Thyratron (BLT), is a low pressure plasma switch having an unheated metallic cathode. In this paper, a computer simulation of the BLT is presented consisting of a 2-1/2 dimensional time dependent continuum model for electron and ion transport. The model utilizes both the local field approximation and a beam component for the electron distribution function. We find that switch closure depends critically on the formation of a virtual anode in front of the cathode hole by generation of positive space charge.
