Paper Abstract

The mirrors for the Einstein Observatory represent a substantial advance in the state of the art x-ray optics, and have been tested more thoroughly than previous telescopes. The image is characterized by a narrow, wavelength independent core, and broad energy dependent wings. The width of the core is about that expected from mechanical and visible light measurements taken during fabrication and assembly. The wings of the response function are caused by microscopic surface scattering, but only a qualitative understanding of this process exists. Improvement in surface texture to reduce the wide angle scatter is the most urgent task in the development of large x-ray optics. The mirrors have survived the experiment integration period and launch, and are performing in orbit as they performed upon the ground.
