What is it about?
Compact, high-performance (i.e., high power per unit of weight and/or volume), centimeter- and millimeter- wave amplifying vacuum electronic devices use sheet or flat (ribbon) electron beam. To compete with self-oscillating magnetrons in power and compactness such devices need to be energized with a correspondingly designed electron gun as an injector (or source) of electrons at comparable perveance.

Why is it important?
We have shown for the first time that a low-loss, high aspect ratio (>12), diode-type electron gun (E-gun) can be built to energize such devices using the same pulsed power supplies (modulators) designed for common or conventional magnetrons having similar beam current and voltage (perveance).
