Design and simulation of nested x-ray mirrors

We present in this paper the basic principle of novel X-ray optics composed of confocal nested reflecting mirrors that allows more photons from a source of X-ray radiation to be accepted compared with a single mirror and that can be fabricated using relatively cheap microfabrication tools. In order to optimize relevant parameters of the proposed system, we developed a ray- tracing code for nested surfaces. The choice of parameters of the mirror system (length, position, eccentricity, etc.) is carried out starting from theoretical considerations, which have been recently developed and, through simple equations, give optimal parameters of X-ray mirrors providing a maximal acceptance angle of the system.
