Design study of accelerator electron guns
In part I of this thesis the theory underlying electron beam design is presented. The paraxial ray equation is derived, and is used to determine the focal properties of an aperture and of an Einzel lens, both of which are assumed to be thin lenses. An aperture can exert a positive or a negative foc...
