A digital computer program for the simulation of charged particle beams in complex electrostatic lens systems is described. A large matrix is employed to simulate the potentials in rectangular or axisymmetric configurations, and relativistic trajectory computations are employed to simulate beams or charged particles of any energy. The beam may be injected with any energy or spatial distribution, including point sources. The program is intended to be an engineering tool which will produce results with an accuracy of one or two percent with modest effort in setting up the problem. Simulations of a CDC 6600 typically require 2 min or less, and complete solutions including plots of trajectories and equipotentials are frequently obtained im less than 30 sec. Results for some specific cases are shown to be within 2% of experimental or exact analytical results. (auth)
