Paper Abstract

This article presents the design and simulated performance of a two-dimensional x-ray shearing interferometer wavefront sensor. In particular, this phase sensitive x-ray wavefront sensor is evaluated for its ability to perform metrology on the DT ice layer in an inertial confinement fusion capsule. The interferometer uses crossed phase gratings in a single plane and is capable of operation over a wide range of x-ray energies by varying the grating material and thickness. The wave-front sensor is insensitive to vibrations and, unlike X-RayTalbot interferometers, recovers the full two-dimensional phase profile of the x-ray beam rather than the gradient in only one dimension.
