Paper Abstract

The telescope mirror for the X-Ray Spectrograph Spectrometer Telescope System is a sixty degree sector of an extreme off-axis paraboloid of revolution. It was designed fo focus a coronal region 1 by 10 arc seconds in size on the entrance slit of the spectrometer after reflection from the gold surface at a glancing angle of about 2.9 degrees. This paper discusses the design, manufacture, and metrology of the mirror, the methods of precision mechanical metrology used to focus the system, the mounting system which serves to locate the mirror and has proven itself through several vibration tests, and the results of reflection efficiency measurements at 8 and 44 Angstroms, and alignment tolerances and ray trace analysis of the effects of misalignment. The mirror was developed under NASA Contract NAS2-9181.
