Abstract :
Summary form only given. In this paper 2-D calculations with self-consistent inclusion of space charge effects and 3-D calculations (without space charge) are presented to show how electron optics codes for PC´s can be used to investigate the effect on the electron focal spot characteristics of tube voltage and current, cathode cup geometry, and emitting surface location and geometry. Similar studies can reduce the time (hence, cost) to establish an optimal tube design by minimizing trial and error cathode cup engineering and testing.
