Paper Abstract

An X-ray spectrometer which is sensitive in the 0.5-7 keV energy range has been studied. The rays which are Bragg reflected from a doubly bent crystal positioned downstream of the focal plane of a grazing-incidence concentrator are focused along the axis of a position sensitive detector. High throughput, simultaneous (scanning free) photon recording throughout the spectral range of interest, and crystal limited resolution which is achieved with a concentrator using a conical approximation to Wolter-1 optics are the main advantages. The sensitivity for spectral line detection in the presence of background may compete with that of broadband detectors.
