On a New Type of X ~ Ray Generator
The principle of the described X-ray generator is a variation upon the direct-current inductor, the grid-controlled X-ray tube itself acting as the interrupter. The anode of the X-ray tube is connected to a constant-voltage generator via a high-inductance coil. The capacitance is constituted by the sum of the capacitances of the tube, the leads and the coil. The main feature of the X-ray tube i...
متن کاملIdentification of glass and ceramics by X-ray fluorescence analysis with a pyroelectric X-ray generator.
Applications of X-ray fluorescence (XRF) analysis with a pyroelectric X-ray generator are presented. Glass and ceramics were analyzed with this novel X-ray generator to examine its capability for analyzing nonmetallic inorganic material. Although the power of X-ray output was a few orders of magnitude lower than conventional X-ray tubes, many elements such as Si, K, Ca, Ti, Cr, Fe, Zn, Sr, Ba, ...
متن کاملHigh Power X-ray Generator for Xafs Experiments
X-ray absorption fine structure (XAFS) provides information on the atomic-scale structure around a specific atom, and has become an essential analytical tool in materials, biology and many other sciences [1, 2]. The availability of a synchrotron source has facilitated the application of XAFS, because a strong smooth spectral distribution is important for the measurements, and synchrotron radiat...
متن کاملX-ray absorption spectral analysis with a 9 V battery X-ray generator.
X-ray absorption spectral (XAS) analysis is performed with a combination of a 9 V dry electric battery X-ray generator and a portable Si PIN X-ray detector. The calcium K edge (4.0 keV) in paper is measured with a grazing incidence geometry, which suppressed the artifact due to the Kalpha X-ray fluorescence peak at 3.5 keV. The 9 V dry battery X-ray emitter is useful for portable XAS measurements.
