Design And Manufacture Of X-Ray Compound Refractive Lens

The x-ray compound refractive lens is a novel refractive x-ray optical device. With the development and application of the x-ray compound lens, x-ray compound lens may find a large spectrum of applications in research and technology.With the data of atom scattering factors, optical constants of some useful material for x-ray compound lens in high-energy X-ray waveband were calculated. It is important to predict the intensity distribution in focusing plane for designing the x-ray compound refractive lenses. On the basis of analyzing the structure of x-ray compound lenses and comparing it with Fraunhofer diffraction system, it is concluded that the x-ray focusing system can be regarded as a kind of Fraunhofer diffraction system. Therefore, a method based on Fourier spectrum analysis is presented to predict the intensity distribution in the focusing plane for the x-ray lenses.The relationship between the parameters of Cu x-ray compound lens and its performance is analyzed. The x-ray compound lens presented in this paper is proposed for sub-micrometer focusing of high-energy x-rays...
