Design and Optimization Electron Guns and Depressed Collectors Using the MICHELLE code in the ANALYST Environment

Electron gun and multistage depressed collector design remain significant tasks in new vacuum electron device development. The ability to accurately predict device performance continues to improve. Recent work has been done on improving the ability for modeling and design simulation environments to aid the designer in finding optimum configurations. As the simulation tools have improved to enable first- pass design success in some cases, the potential benefits of optimization techniques become even more significant. This paper discusses various procedures for optimization of electron guns as well as multistage depressed collectors.
