    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.

    Abstract: An X-ray anode includes a coating and a support body. In addition to a strength-imparting region, the support body has a region formed of a diamond-metal composite material. The diamond-metal composite material is formed of 40 to 90% by volume diamond particles, 10 to 60% by volume binding phase(s) formed of a metal or an alloy of the metals of the group consisting of Cu, Ag, Al and at least one carbide of the elements of the group consisting of Tr, Zr, Hf, V, Nb, Ta, Cr, Mo, W, B, and Si. The highly heat-conductive region can be form-lockingly connected at the back to a heat-dissipating region, for example formed of Cu or a Cu alloy. The X-ray anode has improved heat dissipation and lower composite stress.
