Abstract

Detailed computer simulation of field emission sources has been carried out using the CP03D program. The program computes the potential distribution, the field distribution and electron trajectories in arbitrary electrostatic systems. The calculations have revealed very strong dependence of the electrostatic field on the cathode tip diameter. The field dependence on the distance between the cathode tip and an anode plate is also essential. The size of the anode aperture affects rather little the electrostatic field strength.
