抄録

A numerical simulation method for 3-D electron optics in an electromagnetic field is described. The method features the following: (1) electric field analysis by a boundary-fitted coordinate transformation method in conjunction with a domain decomposition and overlapping technique; (2) consideration of the space-charge effect due to the electron beam in a self-consistent electric field; (3) magnetic-field analysis based on a current sheet method and a boundary-element method; and (4) interactive geometric modeling and numerical grid generation based on the same method as the electric field analysis. The method has been applied to electron optics simulation for the electron gun of a cathode ray tube with a typical deflection yoke. A comparison between computed and measured screen spot profiles verifies the method and demonstrates its capabilities.
