Abstract: "A program has been developed for the IBM 709 digital computer to handle many of the problems encountered in the optical design of high-energy particle beams. The program employs a six-dimensional vector space that takes into account the position and direction in both planes perpendicular to the beam direction, chromatic aberrations and particles of different mass. The quadropole problem with one or two degrees of freedom (i.e., one or two singlets, a doublet, or a symmetric triplet) is solved for the field gradients necessary to yield given beam conditions. The vectors are evaluated at the end of each element in the system. Effects higher than first-order, with the exception of second-order chromatic aberrations in the quadrupoled, are not included. The effect of apertures is calculated in terms of the limitations on the phase-space volume that can be transmitted by the system."
