Paper Abstract

We have developed compact soft x-rayfEUV (XUV), and far-ultraviolet (FtJV) multilayer coated telescopes for the study of the solar chromosphere, corona, and corona/solar wind interface. Because they operate at short wavelengths (4O A < ). < 1550 A), the modest apertures of 40 mm - 127 mm allow observations at very high angular resolution (0.1 - 0.7arc second). In addition to permitting traditional normal incidence optical configurations such as Cassegrain, Ritchey-Chrétien and Herschelian to be used at soft x-ray/EUV wavelengths, multilayer coatings also allow a narrow wavelength band (A/AX -45 - 100) to be selected for imaging. The resulting telescopes provide a very powerful and flexible diagnostic instrument for the study of both the fine scale structure of the chromosphere/corona interface, and the large scale structure of the corona and corona/solar wind interface. In previous papers we have described a new solar rocket payload, the Multi-Spectral Solar Telescope Array (MSSTA) composed of 17 of these compact telescopes. In the present paper, we report on the performance of the 7 MSSTA Ritchey- Chrétien telescopes. Subject terms: Multilayers, XUV, far ultraviolet, solar corona
