Research Institution
High-performance vacuum electron devices, such as microwave tubes, are widely used in military electronic battle-space systems. These devices are found in radar, communications, remote sensing, and navigation systems, where they provide an efficient and reliable source of microwave power. The pivotal role of microwave tubes in many on-board systems makes them a natural choice for careful optimization. Unfortunately, presently available software for modeling beam devices does not support the robust, automated optimization capabilities required for optimal tube design. To address this critical need, we will link modern statistical optimizers to several established codes used for modeling microwave tube guns, collectors, and interaction circuits. The new capabilities will be integrated within a commercial electromagnetics package, leveraging its existing extensive support for design analysis. This system will allow three-dimensional parametric shape optimization in guns and collectors, optimization of external parameters such as collector plate voltages, and the optimization of interaction circuits. These capabilities will reside within a tightly integrated design environment that includes support for geometry definition, automated meshing, adaptive mesh refinement, and result visualization and post-processing.
