Abstract

The present paper applies a constrained variable metric method (CVMM) for the optimization design of image tubes with electrostatic focusing, and a multigrid method (MGM) for the computation of the electrostatic field in designing image tubes, thus to improve the efficiency of field computation and to reduce the time of computation. For the design of diode tubes, triode tubes, zoom tubes, and gated tubes, we have investigated the objective function having a least-square-fit form with weight factors to carry out the optimization computation. The result of optimization has shown that the suggested method for designing image tubes given in the present paper ia a practical and effective one.
