23 December 2003 Double gradient multilayers for broadband focusing
Author Affiliations +
We have designed and fabricated a new type of focusing multilayer mirror, capable of reflecting a divergent beam over a large energy band around 9 keV. A flat energy response about 10% wide and providing a reflectivity of 50% has been achieved by a non-periodic bi-layer sequence while a lateral thickness gradient follows the varying Bragg condition over the whole mirror length. The focusing setup is based on a simple one-point bender and a pre-shaped substrate. A focal spot size of about 8 micrometers has been obtained at a distance of 285 mm from the center of the mirror using synchrotron radiation from an undulator source. Energy dependent scans have shown that this device enables focusing experiments with fixed geometry at variable energies.
