Various disclosed embodiments include thermionic energy converters and electronic circuitry for generating pulses for igniting plasma in a hermetic package of a thermionic energy converter. In various embodiments, an illustrative thermionic energy converter includes a hermetic package charged with a non-cesium gas additive. The hermetic package is configured to route into the hermetic package pulses for igniting plasma in the hermetic package. A cesium reservoir is disposed in the hermetic package. A cathode is disposed in the hermetic package and an anode is disposed in the hermetic package.

Time-dependent plasma systems and methods for thermionic conversion

Disclosed embodiments include vacuum electronic devices, methods of operating a vacuum electronic device, and methods of fabricating a vacuum electronic device. In a non-limiting embodiment, a vacuum electronics device includes a cathode and an anode. At least one focus grid is disposed between the cathode and the anode, and the at least one focus grid is physically disconnected from the cathode. The at least one acceleration grid is disposed between the cathode and the anode, and the at least one acceleration grid is further disposed adjacent the at least one focus grid. The at least one acceleration grid is physically disconnected from the cathode.

Electrostatic grid device to reduce electron space charge

Disclosed embodiments include vacuum electronics devices and methods of fabricating a vacuum electronics device. In a non-limiting embodiment, a vacuum electronics device includes: an electrode; a plurality of grid supports disposed on the electrode, each of the plurality of grid supports having a first width; and a plurality of grid lines, each of the plurality of grid lines being supported on an associated one of the plurality of grid supports, each of the plurality of grid lines having a second width that is wider than the first width.
