Abstract

The performance goals of the Advanced X-ray Astrophysics Facility (AXAF) require that the Wolter I optics support system be insensitive to temperature fluctuations and the effects of gravity during ground testing. Previous work has shown that acceptable concepts are achievable but require much attention to design details. This paper discusses a new support system wherein each optic is held by a single circumferential ring near its center of mass rather than a multipoint support as previously analyzed. The thermal sensitivity of this system is considerably lower than any concept yet studied. This advanced support concept allows the use of a wider variety of materials and simple design details. Structural analysis utilizing the finite element method and optical ray-trace analysis are used to predict the system performance.
