Abstract: An electron multiplication apparatus uses a matrix of dielectric particles interspersed with conductive particles. Typically a porous layer of metal oxide and relatively inert metal, the material provides high electron count rates while maintaining good temperature stability. The layer is located between a cathode and an anode that together provide desired voltage differentials. A mesh is also used on a side of the matrix layer opposite the cathode to conduct surface charge away from the matrix, while providing an intermediate voltage potential between that of the anode and the cathode. A voltage source is used to generate the voltage potentials for each of the anode, cathode and mesh layer, and the resulting electric fields provide a device that may be used in the detection of high energy particles and photons, such as x-rays. A preferred method of fabricating the material involves the codeposition of a metal prone to oxidation and a relatively inert metal to form a porous layer. A subsequent oxidization step results in a metal oxide being intermingled with a conductive material. The resulting matrix has a high counting rate, but maintains a negative temperature coefficient.

Abstract: In an X-ray diffractometer that reads an X-ray diffraction image by storing and recording the image on a stimulable phosphor, it is possible to realize higher speed of a series of process operations of exposure—read—erase relatively easily and also realize simplification and a small size of a constitution of the diffractometer. The X-ray diffractometer stores and records an X-ray diffraction image on an imaging plate 40 formed of a stimulable phosphor. The imaging plate 40 is installed on a predetermined exposure stage, an eraser 60 is installed behind the imaging plate 40, and a Tear side of an area where the image is stored and recorded is made light transmissive. Whereby, the eraser 60 conducts erasing operation in the area where the image is stored and recorded by irradiating a rear surface of the imaging plate 40 with an erasing light.

Abstract: An x-ray source provides both a line focus output and a point focus output, and is mounted on a rotatable support to allow easy changing between the two. A housing has ports at different angular positions relative to an anode, and each port has an associated optic appropriate for an x-ray beam passing through that port. Three or four ports may also be used to allow for different types of beam conditioning. The different beam optics may also do conditioning based on wavelength, and the anode may be of a composite material to provide different wavelength ranges. The rotatable support may be manual or motorized, and a lockout mechanism may be used to ensure that only one port is active at a time. The support may also be located on a movable table that is movable in multiple perpendicular directions.

Abstract: A multiple wavelength X-ray source includes an electron-generating cathode and an anode with multiple target regions, each of which emits X-rays at a different characteristic wavelength in response to the electrons. The different X-ray radiation outputs are focused by different focusing sections of a focusing optic. The multiple focusing sections are in different respective locations, and each focuses its respective X-ray radiation onto a sample. The focusing sections may be side-by-side mirrors in a Kirkpatrick-Baez configuration, or in a single-bounce, doubly curved elliptical configuration.
