The Advanced X-ray Astrophysics Facility
Abstract
NASA's Advanced X-ray Astrophysics Facility (AXAF), scheduled for launch in the early 1990s, will be an X-ray observatory built around a large-area, high-resolution grazing incidence X-ray telescope. The heart of the AXAF will be an X-ray telescope consisting of six nested Wolter type I paraboloid-hyperboloid pairs ranging in diameter from 0.6 to 1.2 m. The rsulting geometric collecting area will be 1700 sq cm and the focal length will be 10 m. Potential AXAF instruments are presented.
