X-ray crystal spectroscopy with stationary-state single-crystal utilizing Laue diffraction

A new type of x-ray crystal spectrometry has been designed to characterize a hard x-ray spectrum of each pulse emission from a laser-induced plasma x-ray source. Utilizing the Laue diffraction and a two-dimensional detector, it makes possible the measurement of diffracted monochromatic x rays without any time difference using a single crystal in a stationary state. Thus, a hard x-ray spectrum in the range of a wide wavelength can be processed in a very short time period, although the obtained spectrum consists of discrete values. A demonstration of the performance of the proposed spectroscopy was carried out using a conventional x-ray source and a diffractometer. (C) 2001 American Institute of Physics.
