  • ADAPTIVE X-RAY OPTICS
    Publication number: 20100012863
    Abstract: The invention relates to an adaptive optical device for the reflection of impinging radiation, the adaptive optical device comprising at least one actuator and at least one partially reflective volume. The at least one partially reflective volume has a first surface that is oriented to the impinging radiation. The at least one partially reflective volume is at least partially deformable by said at least one actuator such that the impinging radiation is reflected at the at least one partially reflective volume substantially in accordance with Bragg's law. Further, the invention relates to a method and apparatus for controlling the shape of an adaptive optical device.

  • Laser x-ray source apparatus and target used therefore
    Publication number: 20060233309
    Abstract: The invention teaches a x-ray source apparatus (50) with a continuous target (10). The continuous target (10) is hit on a first side (60) of the continuous target (10) by a photon beam (30) from a photon source (20). X-rays (80) are emitted from the continuous target (10). The emitted x-rays (80) are extracted from the x-ray source apparatus (50) from a second side (70) of the continuous target (10). The first side (60) of the continuous target (10) and the second side (70) of the continuous target (10) are opposite sides of the continuous target (10). The used continuous target (10) comprises nano particles.
