摘要： An x-ray imaging system includes a detector positioned to receive x-rays, and an x-ray tube coupled to a mount structure. The x-ray tube is configured to generate x-rays toward the detector and includes a target, a cathode cup, an emitter attached to the cathode cup and configured to emit a beam of electrons toward the target, the emitter having a length and a width, and a one-dimensional grid positioned between the emitter and the target and attached to the cathode cup at one or more attachment points. The one-dimensional grid includes a plurality of rungs that each extend in a direction of the width of the emitter, and the plurality of rungs are configured to expand and contract relative to the one or more attachment points without substantial distortion with respect to the emitter.

摘要： A system and method for controlling the temperature of both an electron emitter and a filament to their lowest possible operating temperature is disclosed. The apparatus includes a filament, an electron emitter heated by the filament to generate an electron beam, and a power supply configured to supply power to each of the filament and the electron emitter. The apparatus also includes a control system to control a supply of power to each of the filament and the electron emitter, with the control system being configured to receive an input indicative of a desired electron emitter operating temperature, cause a desired voltage to be applied between the electron emitter and the filament, and cause a desired voltage to be applied to the filament based on the desired emitter element operating temperature, so as to minimize an operating temperature of the electron emitter and the filament.

摘要： A method for fabricating a component is disclosed. The method includes: providing a member having an effective work function of an initial value, disposing a sacrificial layer on a surface of the member, disposing a first agent within the member to obtain a predetermined concentration of the agent at said surface of the member, annealing the member, and removing the sacrificial layer to expose said surface of the member, wherein said surface has a post-process effective work function that is different from the initial value.
