In the past 30 years, electric propulsion use in spacecraft has grown steadily wordwide1. Modeling and simulation techniques have been playing a more and more important role in developing advanced electric thrusters. In this paper, three-dimensional finite-element simulation of ion thruster optics system is introduced.
Some developments to the Electron Optics Simulator (EOS) in high-Performance Computing (HPC) are illustrated in this paper, including LU decomposition, 64-bit Computing and multicore Parallel Computing.
Recent developments to the electron optics simulator (EOS), an electron gun and collector design tool, are reported in this present. The code has been formally released at 2007, and there are some modifications and new methods to improve the code up to now.
Electron optics designer (EOS) (Tao Huang et al., 2007) is a fully three-dimensional (3D) finite- element (FE) steady- state trajectory code, which is a solver of electrostatic field and trajectory that takes into account secondary electron, space-charge effect and external magnetic field. To validate the code, this paper illustrated two typical experimental verifications of electron gun and collector.
Microwave tube simulator suite (MTSS) is a fully featured software package for microwave tube analysis and design. it consists of four modules now, microwave tube design environment (MTDE), electron optics simulator (EOS), high frequency circuit simulator (HFCS), and beam-wave interaction simulator (BWIS).
