Abstract
We present results of the experimental tests of various arrays of reflectors acting as X-ray optical elements. Planar reflectors were aligned with a common center of curvature to create a 1D focusing array. The experiments were carried out using X-ray radiation in the spectral range 3.5 keV to 7 keV produced at beamline X-27C of the National Synchrotron Light Source at the Brookhaven National Laboratory. The initial beam had width of 90 mm, a focal distribution had a width of 8 mm and a maximum intensity gain of 7.3, as measured with a 0.4 mm diameter pinhole. An X-ray beamsplitter consisting of arrays of reflectors has also been designed and tested. The separation of X-ray beams is 40 mrad and intensity of each of two beams is about 0.32 of the original X-ray beam.
