Abstract: In color monitor tubes, electron optical system influences the quality of the whole tube directly. In the wake of development of HDTV and graphic display in workstation, the quality of color monitor (display) tubes must be improved. For achieving display with high resolution, an axiasymmetric electron optical system is adopted to decrease the size of spot on screen. This paper uses SEU-3D program to simulate electron optical system in color monitor tubes. Taking account of the characters of electron optical system in color monitor tubes, this program uses some special methods to analyse the system so that the result obtained from the simulation can fit the actual condition properly.

Key words: electron optical system, color monitor tubes, high resolution, axi asymmetric system
