Abstract:

In this paper are presented the results of numerical computations of the effect of space charge upon the image size and image distance in a converging beam of charged particles. The minimum beam radius image size and its position image distance are plotted as a function of beam perveance ranging from 10 to the minus 13th power to 0.000001. The beam convergence angle was varied from about 0.03 to 0.15 radians and calculations were carried out for 3 values of aperture radius 0.1 cm, 0.25 cm and 0.50 cm. The results are given for electrons, 1H, 7Li, 20Ne, and 85Rb. Author
