Paper Abstract

We present our design scheme and fabrication of non-periodic multilayer with broad angular or energy bandwidth to demonstrate the potential application of such kind of multilayer for the hard X-ray telescopes. By using a proper optimization process, a non-periodic multilayer with boxcar angular response has been successfully designed. Such structure may provide 16% reflectivity with grazing angle from 1.0 to 1.5deg at energy point of 8.05keV. We also fabricated this structure by using our DC magnetron sputtering machine and tested it in our X-ray measurement system. The result shows a flat and smooth boxcar response in target band with standard deviation of 0.76%, which is convincing that such designing and fabrication processes we established can be applied to the supermirror with a flat boxcar response against the X-ray energy.
