Abstract: An x-ray transmission device includes two surfaces in frictional contact within a low fluid pressure environment provided by a housing substantially opaque to x-rays. Materials of the two surfaces are selected such that the frictional contact generates relative charging between the surfaces. The housing includes a window substantially transparent to x-rays, and an electron target, for example a metal, is on an interior surface of the window. The electron target faces the surface that is relatively negatively charged, such that electrons accelerated from that surface, or accelerated due to the negative charge of that surface strike the electron target to generate x-rays, which may be transmitted through the window.

Abstract: An X-ray emitter is suitable for evenly sterilizing large volumes of material in a short time, the emitter having an elongated X-ray target window and correspondingly elongated electron source mounted in a vacuum chamber. The electrons from the electron source are accelerated towards the X-ray target window, which generates X-rays directed outward from the vacuum chamber when irradiated by electrons from within the vacuum chamber. The elongated form of the electron source ensures that an evenly distributed beam of electrons, with a substantially constant linear distribution over the length of the electron source, arrives at the elongated X-ray target window such that a correspondingly even distribution of X-rays is generated from the X-ray target window. The X-ray target window includes a support substrate, and carries an X-ray target layer made of a target material such as tantalum or tungsten on its inner surface. A process for manufacturing the X-ray emitter is also described.

Abstract: An X-ray emitting target including a diamond substrate, a first layer disposed on the diamond substrate and including a first metal, and a second layer disposed on the first layer and including a second metal whose atomic number is 42 or more and which has a thermal conductivity higher than that of the first metal. Carbide of the first metal is present at a boundary between the diamond substrate and the first layer. The target is prevented from overheating, so that output variation due to rising temperature is suppressed. Thus it is possible to emit stable and high output X-rays.

Abstract: A rotatable anode for an X-ray tube comprises a first unit (901) for being hit by a first electron beam, and at least a second unit (902) being hit by at least a second electron beam, the second unit being electrically isolated from the first. In addition, an X-ray system comprises the anode, a main cathode for generating an electron beam, and first electrical potential, and an auxiliary cathode for influencing a second electrical potential. The main cathode deflects the electron beam to heat the auxiliary cathode. Furthermore, a device determines electrical potential by detecting a point of impact of the electron beam onto the anode and/or by detecting an X-ray spectrum of radiation starting from the anode. The electron beam hits the first unit and is deflected, wherein the deflected beam hits the second unit the point of impact. The first unit and/or second unit emit radiation.

Abstract: A wavelength-classifying type X-ray diffraction device bombards a sample with characteristic X-rays generated from an X-ray generation source, and detects characteristic X-rays diffracted by the sample using an X-ray detector. The X-ray generation source is composed of several metals of different atomic number, respective metals generating several characteristic X-rays of different wavelengths. An X-ray detector is composed of several pixels for receiving X-rays and outputting pulse signals corresponding to X-ray wavelengths. Pixels are respectively furnished with classification circuits. The classification circuits classify and output pixel output signals based on each of characteristic X-ray wavelengths. X-ray intensity is detected on a per-wavelength basis in individual pixels 12. Measurement data based on different wavelength X-rays are acquired simultaneously in just one measurement. Data of diffracted X-rays of different wavelengths are acquired using the entire region of the receiving surface of a two-dimensional detector.
