The new 3D electron gun and collector modeling tool: MICHELLE
J. Petillo,K. Eppley,D. Panagos,P. Blanchard,T. McClure,A. Mondelli,Eric Nelson,N. Dionne,J. DeFord,Ben Held,L. Chernyakova,S. Humphries,J. Burdette,M. Cattelino,Richard True,Khanh T. Nguyen,B. Levush +16 more
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.

Recent advances in the MICHELLE 2D/3D electron gun and collector modeling code
J. Petillo,K. Eppley,L. Chernyakova,D. Panagos,J. Burdette,Eric Nelson,Xiaoling Zhai,N. Dionne,M. Cattelino,J. DeFord,Khanh T. Nguyen,Ben Held,B. Levush +12 more
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.
Proceedings ArticleDOI
Application of the 2D/3D MICHELLE code to electron gun and collector modeling
J. Petillo,K. Eppley,D. Panagos,Eric Nelson,N. Dionne,J. DeFord,Ben Held,L. Chernyakova,J. Burdette,Xiaoling Zhai,M. Cattelino,Khanh T. Nguyen,B. Levush +12 more
TL;DR: In this article, the focus of the development program is to combine modern finite element techniques with improved physics models, and the code employs a conformal mesh, including both structured and unstructured mesh architectures for meshing flexibility, along with a new method for accurate, efficient particle tracking.
