Title: Parallel X-ray Nanotomography.

Abstract: An apparatus for nanotomography uses an x-ray source comprising a laser generated plasma. X-rays generated in the x-ray source are collected and focused using a collector optic onto a sample. The collector optic is preferably comprised of Wolter optics combining reflection off an ellipsoid with a reflection off a hyperboloid. X-rays emitted from the sample are focused with an objective lens assembly. The objective lens assembly includes an array of fresnel zone plates. An image formation and acquisition apparatus form an image based on the received X-rays. The array of fresnel zone places is an important feature of the invention, as the array dramatically improves the intensity of the x-rays reaching the detector over a conventional objective lens. A laser-based x-ray source is also key to the invention, generating an x-ray beam of sufficient intensity to provide sufficient counting statistics for a tomographic reconstruction to be obtained.
