28 November 2000 Multilayer optics for hard x-ray astronomy
Author Affiliations +
We are engaged in a program to develop focusing hard X-ray optics for future X-ray astronomy missions (such as the Hard X-ray Telescope of Constellation-X) and have built a DC magnetron sputtering system to deposit multilayers on candidate substrates for future telescopes. Although our emphasis is on the multilayer coating of integral cylindrical optics which will provide the highest spatial resolution, other types of substrates can easily be coated in this system. We present specular reflectivity data (using CuKα X- rays) of W/Si constant d and depth graded-d multilayer depositions on substrates such as thermally formed DESAG glass and Duran glass cylinders. We will present data to show both azimuthal and linear uniformity of these coatings.
