Numerical Solutions of the Potential Distribution within the Vacuum Region of the FEATRON.

Abstract

This report described the development of a coordinate system generation procedure suitable for use in the numerical prediction of the physical operation of the FEATRON. The suitability of the coordinate system is demonstrated by application to a simplified model of the equations governing charge distribution in the vacuum region of a single FEATRON cell. For this purpose, a solution to Laplace's equation subject to mixed Dirichlet and Neumann boundary conditions is presented. The numerical method used is the Linearized Block Implicit method of Briley and McDonald which is also described. Keywords include: vacuum, FEATRON, space charge, semiconductor.
