An ion beam instrumentation simulator as a tool for analyzing and designing ion beam systems

An experimental computer-aided-design system has been used which can significantly aid in the design of ion-source extracting systems, analyzing magnet, or entire source to target beam optical systems. This system is interactive using a terminal to input and retrieve data. The techniques used to solve Poisson type electrostatic problems and to perform magnet analysis through ray tracing prgrams represent state-of-the-art in the numerical analysis of the electrostatic and magnetic geometries most often found in isotope separators and ion implanters. Problems can be run in a self-optimization mode which facilitates the design of beam optical components. Using this system, numerical calculations have been made to analyze the beam divergence characteristics of a source-extractor system of the type used in isotope separators. (Auth.)
