| Abstract: | In this paper,the physical factors of the formation of electron beam spot in an electron optical system were analyzed.Through complicated analysis and calculation we obtained the basic rules of choosing a convergent half angle,an optical system and lens parameters,and learned their effects on the beam spot size.The said analysis and calculating method are also useful to the design of electron optical system of EB welding machines. |
