Computer-Aided Design and Optimization of High-Performance Vacuum Electronic Devices

摘要

We have completed implementation of a variety of numerical optimization methods, including multi-directional search (MDS), differential evolution (DE), the Powell conjugate gradient method, and a zero-crossing technique. These methods have been extensively tested on several guns and collectors. The user interface to these techniques in Analyst has been completed and is included in Analyst Version 10. We have also completed development of a system for computing the manufacturing sensitivity of a design point. To support collector optimization we have recently created capabilities for the Analyst magnetostatics solver (MS3P) to output magnetic field files in a format that MICHELLE can read, and we have worked with SAIC on modifications to MICHELLE to use these files. This report was developed under a SBIR contract award for Solicitation topic N04-113.
