Paper Abstract

Low energy monochromatic x rays can be ]used to detect the attenuation differences between fibrous, fat, and cancerous tissues in mammography, evaluation of computer processor chips, as well as quality control for micro components. At 17 keV, carcinomas, fibrous and fatty tissues attenuate incident radiation to different degrees which permits non invasive detection of cancerous tissue. A sliced transmission multilayer grating is presented that produces monochromatic x-ray radiation at 17 keV. The sliced multilayer utilizes the coincidence of Bragg and diffraction orders to achieve higher efficiency and resolution than a conventional grating. A classical multilayer consisting of low and high atomic number materials along with a monomaterial multilayer in which the density of the material is varied to simulate two different layers are presented.
