Paper Abstract
New hybrid model for three electrodes gun was developed. It was called as Equivalent Cylinder Model (ECM). It allows to find field distribution and its derivatives analytically and gives useful information about electron gun paraxial properties as well as nonparaxial ones. The aberrations coefficients dependence on bias values was calculated. Current density radial distributions are discussed briefly. This model can be useful for design of devices working under Koehler mode.
