摘要： A method is for detecting high-voltage flashovers in X-ray equipment including an X-ray emitter and a high-voltage supply. The X-ray emitter has an X-ray tube, surrounded by an insulating medium; and the high-voltage supply has a high-voltage generator and a cable. The cable is at least part of a connecting passage between the high-voltage generator and the X-ray tube. During normal operation of the X-ray equipment, an interference pulse, which occurs due to the high-voltage flashover in the connecting passage, is detected and evaluated with the aid of a measuring device, including a measuring element. As such, an assessment of the condition of the X-ray emitter and of other high voltage-carrying components, and measures that follow, are made using the evaluated interference pulse.

摘要： An x-ray tube casing is provided which includes a housing having a heat exchanger integrally formed thereon in an additive manufacturing process. The additive manufacturing process allows for tight tolerances with regard to the structure for the casing and the internal passages of the heat exchanger to significantly reduce the size and weight of the casing. The casing additionally includes a fluid distribution manifold that effectively distributes the cooling fluid within the casing to more efficiently provide cooling to the x-ray tube insert disposed within the casing.

The support structure comprises a recess for receiving the port extension, the recess also framing an opening for x-ray transmission. The imaging system may be a computed tomography (CT) imaging system, x-ray diagnostic system, or other imaging system.

摘要： A scintillator panel has a barrier rib structure, whereby opposing light-receiving substrates can be aligned with high precision and bonded with a photoelectric conversion element. In the scintillator panel, cells demarcated by lattice shaped barrier ribs formed on a sheet-shaped base member are filled with a phosphor for receiving radiation and emitting light, thereby configuring a pixel structure. The scintillator panel has portions in which the lattice-shaped barrier ribs are exposed on both a front surface and a back surface in a portion of a non-display region of the panel external periphery. The exposed parts are optically transparent.

摘要： An X-ray source uses excitation of a liquid metal beam of ions or ionized droplets to produce an X-ray output with higher brightness than conventional sources. The beam may be accelerated from a liquid metal source using an extraction electrode. The source may have an emitter tip, and the acceleration of the liquid metal may include field emission from a Taylor cone. An electrostatic or electromagnetic focusing electrode may be used to reduce a cross-sectional diameter of the beam. The liquid metal beam has a relatively high velocity as it does not suffer from flow turbulence, thus allowing for a more energetic excitation and a correspondingly higher brightness. A beam dump may also be used to collect the liquid metal beam after excitation, and may be concave with no direct sight lines to either an electron beam cathode or to X-ray windows of an enclosure for the source.

摘要： An XRF analyzer can include an x-ray source and an x-ray detector; an x-ray source heat-sink adjacent a side of the x-ray source; and an x-ray detector heat-sink adjacent a side of the x-ray detector. In one embodiment, the x-ray source heat-sink can be separated from the x-ray detector heat sink by a material having a thermal conductivity of less than 20 W/(m*K). In another embodiment, the x-ray source heat-sink can be separated from the x-ray detector heat sink by at least 3 millimeters of a thermally insulating material. In one embodiment, the x-ray source heat-sink can be separated from the x-ray detector heat sink by a segment of the engine component casing. Separation of the heat sinks can help avoid heat from the x-ray source adversely affecting resolution of the x-ray detector.

摘要： A radiation generating apparatus includes: an envelope 1 having a first window 2 through which a radiation is transmitted; and a radiation tube 10 being held within the envelope 1, and having a second window 15 which is arranged in opposition to the first window 2, and through which the radiation is transmitted; and a radiation shielding member 16 thermally connected to the second window 15, having a radiation transmitting hole 21 arranged in communication with the second window 15, and having a protruding portion protruding from the second window 15 toward the first window 2. A thermally conductive member 17 having a higher thermal conductivity rather than that of the radiation shielding member 16 is connected to the protruding portion of the radiation shielding member 16. The radiation generating apparatus can shield an unnecessary radiation and cool a target with a simple structure and is entirely reduced in weight.
