摘要：

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