Abstract :
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.
