Development of a Focussing Hard X-Ray Telescope

摘要

This contract was the most recent phase of an ongoing program at Radiation Science supported by NASA. The overall objective of this program is the construction of a focussing hard X-ray telescope. We were able to generate replicated surfaces with arc-second range hard X-ray scattering properties. We were able to reflect 15, 30, and 45 keV X-rays from multilayer coatings on thin foils. We were able to separate a multilayer coating deposited directly on a master surface from the surface after electroforming a supporting structure without damaging either the multilayer or the master surface. These developments open the door for the fabrication of a Wolter type I hard X-ray telescope. We conclude that the development of such a telescope should proceed.
