Paper Abstract

A grazing incidence solar X-ray telescope, SXT, will be flown on the Solar-A satellite in 1991. Measurements have been conducted to determine the focal length, PSF (Point Spread Function), and effective area of the SXT mirror. The measurements were made with pinholes, knife edges, a CCD, and a proportional counter. The results show the 1/7. character of the PSF, and indicate a half power diameter of 4.9 arc-sec and an effective area of 1.33 cm2 at 13.3 Å (.93 keV). The mirror was found to provide a high contrast image with very little X-ray scattering.
