TL;DR: In this paper, the authors present a new three-dimensional electron gun and collector design tool, which targets problem classes including gridded-guns, sheet-beam guns, multibeam devices, and anisotropic collectors.

TL;DR: A 3D finite-element gun and collector modeling code, MICHELLE as discussed by the authors, was developed at SAIC in collaboration with industrial partners and national laboratories to address the shortcomings of current beam optics simulation and modeling tools for vacuum electron devices.

TL;DR: The MICHELLE as discussed by the authors code is a new finite-element (FE) two-dimensional and three-dimensional (3D) electrostatic particle-in-cell (PIC) code that has been designed to address the recent beam optics modeling and simulation requirements for vacuum electron devices, ion sources, and charged-particle transport.

TL;DR: The 3D finite-element gun and collector modeling code, MICHELLE as mentioned in this paper, has been developed at SAIC in collaboration with industrial partners and national laboratories to address the shortcomings of current beam optics simulation and modeling tools for vacuum electron devices.

TL;DR: The presentation provides an overview of the program objectives, the approach to be taken by the development team, and a status of the project.
