Integration of Simulation Tools for High Current Electron Sources

DoE researchers are presently designing higher current electron sources for energy and environmental applications, among others. Computer modeling is an important part of this design process, but presently researchers cannot use important tools, like particle-in-cell and particle tracking tools or like time domain and frequency domain tools, easily together. The goal of this project is to make it easier for researchers to import results of one code into another, to exchange results between codes, and to compare results from the di erent codes. Statement of how this problem is being addressed We propose to improve the ability of a set of codes to interface with one another and to develop the ability to display results from multiple codes in a way that makes it easy to compare results. What is to be done in the Phase I In Phase I, we have four main tasks: i) improve the capability to easily couple a frequency domain and time domain code, ii) improve the capability to easily couple a time domain and a particle tracking code, iii) demonstrate optimization of parameters relevant to high current electron sources for these codes, and iv) demonstrate easy to use visualization and analysis of the data from multiple codes. Commercial applications and other benefits One of the modeling tools we plan to use is presently a successful commercial software product, and the improvements we plan in this project will make it even more successful by expanding the market for this tool. For example, the need for high current electron sources in the medical industry is a growing market, and providing a benchmarked tool will allow us to increase the sales of this product.
