Various systems are provided for an X-ray system. In one example, the X-ray system comprising a high-voltage connector physically coupled to a cathode of an X-ray tube via a plurality of pins, wherein the pins comprise niobium.

Methods and systems for an X-ray tube assembly

An x-ray tube having a coated x-ray tube frame inner surface and a coated anode assembly is provided. The x-ray tube includes an x-ray tube frame in which an anode assembly is disposed therein. A cathode assembly is also disposed within the x-ray tube frame that emits an electron beam to strike a target surface of the anode assembly and form x-rays. A plasma-sprayed tungsten oxide coating is formed on an inner surface of the x-ray tube frame and on the anode assembly to dissipate heat created by the electron beam.

An apparatus includes an electron collector includes a body having an internal bore formed therethrough along a first direction and a window side having an aperture formed in a first portion thereof along a second direction different from the first direction. The apparatus also includes a cover plate having a bottom surface coupled to a second portion of the first surface of the electron collector, and an x-ray transmission window coupled to the cover plate and aligned with the aperture along the second direction, wherein a recess is formed along the second direction in one of the first portion of the first surface of the electron collector and a portion of the bottom surface of the cover plate, and wherein a gap is formed between the bottom surface of the cover plate and the first surface of the electron collector.

Thermal energy storage and transfer assembly and method of making same

A system and method for collecting backscattered electrons within a substantially evacuated vessel containing both an electron-emitting cathode assembly and an electron-attracting anode assembly. The system and method comprises an electron collector assembly including a first plate, a second plate, an internal member, a fluid inlet, and a fluid outlet. The first plate is mounted within the vessel closest to the anode assembly. The second plate is mounted within the vessel closest to the cathode assembly. The internal member is positioned between the first plate and the second plate, and includes an internal conduit for conveying a heat absorbing cooling fluid therethrough.

System and method for collecting backscattered electrons in an x-ray tube

An x-ray tube includes an anode comprising a focal track and a cathode assembly configured to emit an electron beam toward a focal spot on the focal track. The x-ray tube also includes a controller configured to wobble the electron beam among a plurality of focal points in a direction tangent to the focal track. The plurality of focal points includes at least one focal point that is bounded by a pair of boundary focal points. The controller is further configured to delay a wobble of the electron beam away from the at least one focal point for a pre-determined amount of time.

Focal spot temperature reduction using three-point deflection

A structure for collecting scattered electrons within a substantially evacuated vessel containing both an electron-emitting cathode and an electron-attracting anode is disclosed herein. The electron-collecting structure includes a two-sided first plate, a two-sided second plate, a fluid inlet, and a fluid outlet. The first plate is both electrically conductive and thermally emissive and is mountable within the vessel so that its first side at least partially faces the anode. The second plate is also thermally emissive and has a first side that is substantially conterminous with the second side of the first plate. Furthermore, the second plate additionally has an internal conduit for conveying a heat-absorbing fluid within. Both the fluid inlet and the fluid outlet are in fluid communication with the conduit in the second plate. During operation, the structure is able to attract scattered electrons and transfer thermal energy attributable to the electrons away from the structure.
