A Multi-Crystal Spectrometer with a Two-Dimensional Position-Sensitive Detector for X-ray Fluorescence Spectroscopy

摘要: A newly designed multi-crystal x-ray spectrometer equipped with a two-dimensional position sensitive proportional counter is described. The employs five cylindrically bent rectangular Ge(4?4?0) crystals 35???100?mm2 in size, whose radius of curvature 550?mm. Diffracted x-rays from each crystal are horizontally dispersed and vertically focused onto different portions the detector, spectra constructed by adding data crystals. Resonant K? emission Mn compounds obtained this presented.
