Paper Abstract

We report on the first high resolution images of the sun in the soft x-ray/extreme ultraviolet (XUV) regime obtained with normal incidence multilayer optics. The images were obtained during a sounding rocket flight on October 23, 1987 from White Sands Missile Range, New Mexico. Multilayer coated optics were used in three different configurations: as optical elements in two Cassegrain Telescopes, as off-axis primary mirrors, and as tertiary mirrors operating with a Wolter Schwarzschild grazing incidence mirror. The inherent energy selective property of multilayer coated optics allowed distinct groups of emission lines to be isolated in the solar corona and the transition region. Images were recorded at 173 A and 256 A with the Cassegrain Telescopes, at 256 A with a Herschelian Telescope, and at 44 A, 173 A and 256 A with the Wolter Schwarzschild hybrid telescope. In addition, soft x-ray images in the 8 - 18 A bandpass were obtained at the prime focus of the Wolter Schwarzschild optics. The images show many features of the solar corona and transition region, including magnetically confined loops of hot solar plasma, coronal plumes, polar coronal holes, supergranulation, and features associated with overlying cool prominences.
