    Abstract: A rotary anode for a rotary anode X-ray tube has an anode disc with a supporting portion. A focal track is located in the vicinity of an outer diameter of the anode disc. The supporting portion has inhomogeneous material properties along a radial coordinate of the anode disc to provide a high mechanical load capacity in the area of an inner diameter of the anode disc and a high thermal load capacity at the focal track. These measures provide for a rotary anode for a rotary anode X-ray tube that meets the extreme thermal and mechanical loads during operation. Further, a method for manufacturing such a rotary anode is described as well.

    Abstract: We disclose a compact source for high brightness x-ray generation. The higher brightness is achieved through electron beam bombardment of multiple regions aligned with each other to achieve a linear accumulation of x-rays. This may be achieved by aligning discrete x-ray sources, or through the use of novel x-ray targets that comprise a number of microstructures of x-ray generating materials fabricated in close thermal contact with a substrate with high thermal conductivity. This allows heat to be more efficiently drawn out of the x-ray generating material, and in turn allows bombardment of the x-ray generating material with higher electron density and/or higher energy electrons, leading to greater x-ray brightness.The orientation of the microstructures allows the use of an on-axis collection angle, allowing the accumulation of x-rays from several microstructures to be aligned to appear to have a single origin, also known as “zero-angle” x-ray emission.

    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. The layer thickness of the first layer is greater than or equal to 0.1 nm and smaller than or equal to 100 nm. 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 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.
