Abstract
A method for estimating the main parameters of a paraxial axially symmetric charged particle beam taking into account the contribution of space charge forces is described. This method is based on the general equation for a beam envelope. The data characterizing its convergence and stability for experimental errors are presented. The errors in determining the crossover position and the beam radius in the crossover do not exceed 15%, and the error in estimating the emittance depends on the relationship between the emittance and space charge forces. This method has been used to estimate the parameters of an actual electron gun with an energy of 50 keV and a current of 0.64 A. The results obtained are in good agreement with the design values. The technique described may be generalized to the case in which axial symmetry is absent.
