Abstract: A thermionic electron emitter (1) is proposed comprising an inner part (2) including a heatable flat emission surface (3) and an outer part (4) including a surrounding surface (6) substantially enclosing the emission surface and a heating arrangement for heating the emission surface to a temperature for thermionic electron emission. The outer part is mechanically connected to the inner part in a connection region (10) apart from the emission surface. Furthermore, the surrounding surface is thermally isolated, e.g. by a gap (14), from the emission surface in an isolation region apart from the connection region. By providing a surrounding surface enclosing the emission surface which may be on a similar electrical potential as the emission surface but which can have a substantially lower temperature than the emission surface without influencing the temperature distribution within the emission surface, an improved electron emission distribution and homogeneity can be obtained.

Abstract: A method of producing a cathode for use in an x-ray tube assembly is provided including machining an emission aperture into a cup emission surface portion of a cup structure. The cup structure is comprised of a cup base portion opposite the cup emissions surface portion. Electro-discharge machining is used to form an electro-discharge machining slot into the cup structure to provide access to the interior of the cup structure. Electro-discharge machining is used to form a transverse coil chamber within the interior by way of the electro-discharge machining slot such that the transverse coil chamber is formed between the cup base portion and the cup emissions surface portion while retaining an essentially contiguous emissions surface perimeter surrounding the emission aperture.

Abstract: A solid-state vacuum device (SSVD) and method for making the same. In one embodiment, the SSVD forms a triode device comprising a substrate having a cavity formed therein. The SSVD further comprises cathode positioned near the opening of the cavity, wherein the cathode spans over the cavity in the form of a bridge that creates an air gap between the cathode and substrate. In addition, the SSVD further comprises an anode and a grid that is positioned between the anode and cathode. Upon applying heat to the cathode, electrons are released from the cathode, passed through the grid, and received by the anode. In response to receiving the electrons, the anode produces a current. The current received by the anode is controlled by a voltage applied to the grid. Other embodiments of the present invention provide diode, tetrode, pentode, and other higher order device configurations.
