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.
