Paper Abstract

A new approach to solve the self-consistent problem for electron gun with arbitrary-shaped cathode is suggested. The main feature of the approach is that the most effective numerical techniques of charged particle optics, namely finite-difference and integral equation methods for field calculation on the one hand, and direct ray-tracing and aberration analysis for trajectory calculation on the other, are integrated within a versatile iterative procedure. Some testing problems are considered and analysed in details.
