Abstract

The detection of point-like celestial sources of hard X-radiation in the presence of background could be improved by many orders of magnitude by using a telescope to concentrate the incoming X-ray flux. Unfortunately, conventional grazing incidence X-ray optics become impractical at energies greater than about 10 keV. We have developed a design concept for a new class of hard X-ray telescope using synthetic multilayer structures as X-ray reflecting elements. A proper choice of multilayer spacing as a function of position allows the telescope to be tuned to a specific X-ray wavelength. Our design is the multilayer analog of a popular, economical, grazing incidence X-ray telescope design. It has the advantage that the multilayers are deposited on flat surfaces of manageable size, unlike previous designs which required the deposition of multilayers on large concave surfaces. We have considered the design of the required multilayer structures, the design of the telescope mirror, and the design of a telescope tuned to 100 keV and sized for a shuttle launch.
