Abstract
By using the expressions of the field parameters and with the aid of the Orthogonal Design Method, we optimized the design of the saddle delection yoke with a ferromagnetic shield. The results obtained agree with the practical model. It is pointed out that the end-ear and the distribution of the fleld parameterB 0 (z) have important effects on the deflection aberrations. An example is given in which the electron optical properties of the deflection coils having cosine- distribution and finite length and that of the deflection coils having distributed winding are compared.
