Abstract
The electron trajectories corresponding to the angular distribution of the emission current are simulated, allowing for self-heating of the cathode an d the influence of space charge on the emission. It is shown that the natur e of the rings is related to the emission from peripheral regions of the ti p (conical section) and to compression of the current from these regions.
