New Deformable Mesh Gun Code Based on Poisson Group Programs.

Abstract

The project described in this report was undertaken with a view that there is a need for a space-charge electron flow computer program that is user friendly, well documented, versatile, and available to the scientific and industrial community. This report presents the project to design and implement a deformable mesh program which solves the electron flow probe. The solution of the space-charge flow problem consists of two parts: 1) Solving Poisson's equation; and 2) Solving the equation of motion for electrons derived from the Lorentz force equation. To solve Poisson's equation, the set of codes developed by Halbach and Holsinger, 'POISSON Group Programs' was used. To solve the Lorentz force equation, the work of True was followed. In this report, the results of the performance of the deformable mesh program are presented. As will be seen, correlation between theoretical and experimental results is very good. Keywords: Traveling wave tubes; Ray tracing; Fortran. (Author)
