X-ray Ultraviolet Imager for the Orbiting Solar Laboratory. (Reannouncement withNew Availability Information)

摘要

A normal incidence multimirror telescope, the X-ray Ultraviolet Imager, for highresolution imaging of the solar atmosphere in the soft X-ray/XUV region, is being developed as part of the scientific payload of the NASA Orbiting Solar Laboratory. The X-ray Ultraviolet Imager is formed by two units: a high resolution telescope and a wide field one. The two systems complement each other and allow a full coverage of solar features from a small scale (200 km on the sun) to the global phenomena. Each system consists of 8 channels with multilayer mirrors, imaging at different wavelengths. In each channel the mirror coating is optimized to select a narrow spectroscopic window corresponding to an intense
