Abstract
An X-ray spectrometer which is sensitive in the 0.5-7-keV energy range and is intended for use onboard astronomical satellites has been studied. The Bragg reflected rays 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. A high throughput concentrator with densely nested thin-foil conical mirrors approximating a Wolter-1 system can be used without loss of spectral resolution. Other advantages include simultaneous (scanning free) coverage of the spectral range of interest, nearly stigmatic imaging, and crystal-limited resolution
