Abstract
The Focal Plane Crystal Spectrometer on HEAO-B is a moderate to high resolution, curved-crystal, Bragg spectrometer which operates behind a grazing incidence x-ray telescope. It is designed to allow detailed spectral studies of both point and extended celestial x-ray sources in the energy range 0.2-3.3 keV, with resolutions of 50 to 1000. The analyzing elements are six torroidal diffractors, and the detectors are position-sensitive, flow, proportional counters. HEAO-B is scheduled for launch in June, 1978.Keywords
