Circuit characterization of magnetically insulated electron flow

We consider a switch characteristic corresponding to magnetically insulated electron flow in a gap between an effective cathode and anode. The current voltage relationship in a circuit containing parallel switch and load elements remains that of the switch independent of the load for load impedance which is not too small. This concept to which the analytic model investigated in this paper conforms is confirmed by two-dimensional PIC calculations for electron flow in a magnetically insulted gap leading into a vacuum feed terminated by a resistive load.
