## Abstract Stacking technique was developed in order to increase focusing efficiency of Fresnel zone plates at high energies. Two identical Si chips each of which containing Fresnel zone plates were used for stacking. Alignment of the chips was achieved by onβline observation of the __moirΓ©__ patt
A monolithic x-ray focusing lens can focus divergent x-rays from a conventional x-ray tube into 110 lm microbeam. A gain factor of more than 1200 compared with an aperture without the lens has been achieved. Using a monolithic x-ray focusing lens combined with aperture optics, a 50 lm microbeam with
