Grazing-Incidence Focusing Mirrors for X-Ray Beams


Grazing-incidence reflective optics are widely used in X-ray beamlines, in particular Kirkpatrick-Baez (KB) elliptical mirror systems [A. Verhoeven, et al., Journal of Synchrotron Radiation 27.5 (2020): 1307-1319]. Focusing is accomplished by using two physically separated elliptical mirrors to focus the beam in two dimensions. The incoming X-rays can be focused by the system down to nanometer-scale spot size. Such system is modeled and simulated in VirtualLab Fusion and the focal field is calculated.
