Abstract

Various types of X-ray focusing optical systems are used at X-ray synchrotron radiation and free-electron laser facilities. However, these are designed for specific purposes and fixed optical parameters such as the numerical aperture (NA). Their lack of adaptability limits their application targets. In this research, we developed an X-ray adaptive focusing optical system which can control the beam size without moving the position of focus. The optical system consists of two deformable mirrors in one dimension. To vary the focused beam size, the NA is controlled by deforming the shape of the mirrors from concave to convex. The results will be presented along with the aberration properties estimated by ray trace and wave optical methods.
