摘要： The present invention refers to an X-ray tube of the rotary-anode type which comprises at least one temporarily negatively biased auxiliary grid electrode (119) with an aperture through which an electron beam (115) emitted by a tube cathode's thermoionic electron emitter (111) can pass. As an alternative thereto, the auxiliary grid electrode (119) may also be positively biased so as to enhance electron emission from a thermoionic electron emitter (111). The auxiliary grid electrode may thereby be connected to a supply voltage UAUX of a controllable voltage supply unit by means of a feedthrough cable (120) serving as a feeding line for providing the main control grid (112) with a grid supply voltage UG.

摘要： An X-ray tube comprises an electron source in the form of a cathodE (12), and an anode (14) within a housing (10). The anode (14) is a thin film anode, so that most of the electrons which do not interact with it to produce X-rays pass directly through it. X-rays can be collected through a first window (16) directly behind the anode (14), or a second window (18) to one side of the anode. A retardation electrode 20 is located behind the anode 4 and is held at a potential which is negative with respect to the anode 14, and slightly positive with respect to the cathode (12). This retardation electrode (20) produces an electric field which slows down electrons passing through the anode (14) so that, when they interact with it, they are at relatively low energies. This reduces the heat load on the tube.

摘要： An X-ray scanning apparatus comprises a number of multi-focus X-ray tubes (25) spaced around an axis X and arranged to emit X-rays through an object on the axis which are detected by sensors (52). Each tube (25) can emit X-rays from a plurality of source positions. In each scanning cycle, in which each of the source positions in each of the tubes is used once, the ordering of the positions used is arranged so as to minimize the thermal load on the tubes (25). This is achieved by ensuring that each source position is non-adjacent to the previously active one and the next active one.

摘要： A novel x-ray treatment system utilizes one or more large area flat panel sources of x-ray radiation directed into a target zone. A target substance within the target zone is irradiated with x-ray radiation from the one or more flat panel sources, reducing the biological effects of a contaminant presence therein. The flat panel source comprises an electron source, an electron accelerator, and an electron target medium. The electron source may emit electrons either via field emission or thermionic emission. The x-ray source may operate in transmissive, reflective, or combined transmissive/reflective mode. The use of large area flat panel x-ray sources in the inventive systems allows for decreased installation and operational costs as well as increased efficiency.

摘要： The present invention relates to an X-ray tube with a structure, by which the charging of an insulating member, disposed inside a container, is effectively prevented to enable stable operation to be secured. This X-ray tube has an electron source that emits electrons, a target that generates X-rays in response to the incidence of the electrons, first and second electrons, each having a side face portion that extends along the direction of incidence of the electrons and forming a predetermined electric field between the electron source and the target, and an insulating support member, for supporting the first and second electrodes, being disposed along the side face portions of the first and second electrodes. The second electrode, of the first and second electrodes, is positioned closest to the target and has an anti-charging edge portion that is positioned at an X-ray generating surface end of the side face portion and that extends toward the exterior of the container so as to cover over the support members from the target.
