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