    Abstract: Disclosed herein are a high-voltage generator for an x-ray source, an x-ray gun, an electron beam apparatus, a rotary vacuum seal, a target assembly for an x-ray source, a rotary x-ray emission target, and an x-ray source. These various aspects may separately and/or together enable the construction of an x-ray source which can operate at energies of up to 500 kV and beyond, which is suitable for use in commercial and research x-ray applications such as computerised tomography. In particular, the high-voltage generator includes a shield electrode electrically connected intermediate of a first voltage multiplier and a second voltage multiplier. The electron beam apparatus includes control photodetectors and photo emitters having a transparent conductive shield arranged therebetween. The rotary vacuum seal includes a pumpable chamber at a position intermediate between high-pressure and low-pressure ends of a bore for a rotating shaft. The rotary target assembly is configured such that when a torque between a bearing housing and a vacuum housing exceeds a predetermined torque, the bearing housing rotates relative to the vacuum housing. The rotary x-ray emission target has a plurality of target plates supported on a hub, the plates being arranged on the hub to provide an annular target region about an axis rotation of the hub. The x-ray gun is provided with a shield electrode maintained at a potential difference relative to the x-ray target different to the electron beam emission cathode.

    Abstract: Die Erfindung betrifft eine Funkenstrecke mit einer Kathode (12) und einer Anode (11). Erfindungsgemäß ist vorgesehen, dass die Funkenstrecke durch ein Mittelstück (13) in zwei Teil-Funkenstrecken unterteilt ist, nämlich einer Hochdruck-Funkenstrecke (14) und einer Nutz-Funkenstrecke (15). Die Nutz-Funkenstrecke (15) kann z. B. zur Erzeugung von monochromatischer Röntgenstrahlung (26) verwendet werden. Um einen definierten Schalzeitpunkt zu gewährleisten, wird die Hochdruck-Funkenstrecke (14) genutzt, die zuerst definiert geschaltet wird. Durch das Schalten steht am Mittelstück ein so hohes Potential zur Verfügung, dass die Nutz-Funkenstrecke (15) beim Schalten der Hochdruck-Funkenstrecke (14) ohne wesentliche Verzögerungen bei einer deutlich überhöhten Spannung ebenfalls definiert geschaltet werden kann.

    Abstract: This invention provides an X-ray generator utilizing a high electric field which is generated upon heating or cooling of a hemimorphic crystal. Unidirectionally polarized lithium niobate crystal (1) and X-ray target (6) are disposed within a casing (8) kept in a vacuum state, and a thorium-containing tungsten wire (7) is disposed between the crystal (1) and the X-ray target (6). When the crystal is heated or cooled by a Peltier element (3), a high level of electric field is generated around the crystal. A thermoelectron released from the tungsten wire is accelerated by the electric field and collides against the X-ray target. The X-ray released at that time is radiated to the outside of the casing through a beryllium window (9). The X-ray generator can generate intense X-ray without using large equipment such as a high voltage power supply.

    Abstract: A nondestructive inspection apparatus with integrated power supply comprises a molded power supply section (14) having a resin-molded high voltage (e.g. 160 kV) generating section (15) secured to the base of a tubular section (2). The durability and handlability are improved by omitting a high voltage cable. Since the high voltage generating section (15) is confined in a molding resin, the degree of freedom in the arrangement of the high voltage generating section (15) within the mold is enhanced significantly. Furthermore, an X-ray generating unit (1) can be installed stably in the nondestructive inspection apparatus (70) by disposing the heavy molded power supply section (14) under a target (10).

    Abstract: [Problem] To provide an X-ray inspection system capable of blocking the effect of heat from an X-ray source, thereby making it possible to place a heat-sensitive circuit component in the same housing space as the X-ray source. [Solution] A housing 10 is provided with an upper housing space 11, in which an X-ray source 32 housed in a cooling container 30 is placed. Owing to pressure of a pump 36, a cooling medium circulates between the cooling container 30 and a heat radiating device 33, suppressing the temperature rise of the cooling container 30. Since the cooling container 30 is placed in the upper housing space 11, the upper housing space 11 serves as a cooling space, suppressing the temperature rise. Therefore, heat-sensitive or heat-producing circuit components can be placed in the upper housing space 11.
