Abstract: The present disclosure can relate to a thermionic emission device. The thermionic emission device can include a substrate layer, an insulating layer deposited onto an uppermost surface of the substrate layer, and an electron emitting layer deposited onto an uppermost surface of the insulating layer. The electron emitting layer, the insulating layer, and the substrate layer each can include a first etching and a second etching oriented according to a photoresist pattern applied to an uppermost surface of the electron emitting layer. The first etching and the second etching can converge to form a cavity in the substrate layer beneath a beam suspended above the cavity. The beam can comprise an unetched region of the electron emitting layer and the insulating layer oriented between the first etching and the second etching.

Abstract: A flat emitter comprises four current-supply heating legs. Half lighting for a small focus in which a current is supplied to heat only a region narrower and full lighting for a large focus in which a current is supplied to heat the entire region are selectable according to the combination of the legs. Either one of a set of the two full-lighting current-supply heating legs for the full lighting and a set of the two half-lighting current-supply heating legs for the half lighting is linearly formed, and the other is formed to be bent plural times in zigzag to set the space between the full-lighting current-supply heating leg and the half-lighting current-supply heating leg, which are adjacent to each other, at their terminals to be larger than the space at their base parts.

Abstract: An electron beam emitter comprises an electron emission source capable of emitting electrons; a vacuum chamber containing the electron emission source; and a transmission window that keeps airtightness of the vacuum chamber and is capable of transmitting the electrons from the electron emission source. The transmission window includes a foil that transmits the electrons and a grid that does not transmit the electrons. The electron emission source includes an emission portion that emits the electrons and a non-emission portion that does not emit the electrons. The emission portion has a lower work function than the non-emission portion. The non-emission portion is prepared so as to prevent the electrons from reaching the grid.
