Highly Space Charge Limited SGEMP Calculations.

Abstract

This report reviews and compares several calculational methods for studying the space-charge-limited SGEMP problem. Included are early-time approximations, steady-state calculations, and finite difference techniques. A boundary layer treatment using steady-state theory is also developed. The report discusses how this boundary layer treatment can be incorporated into a finite difference code in a way that subdivides the finite difference cells next to emission surfaces. This subdivision makes it possible to calculate highly space-charge-limited SGEMP response without requiring extremely fine mesh cells. (Author)
