X-ray microscopic imaging of low Z material wrapped by strongly absorbing medium

Abstract

It is difficult for the nondestructive detection of inertial fusion capsule. Based on this requirement we constructed a physical model of low Z material wrapped by strongly absorbing medium. By simulation and experiments，we investigate the effect of some factors on phase contrast imaging quality，such as X-ray energy，distance of object to detector, thickness of strongly absorbing materials and so on. We find it feasible to realize the high resolution and nondestructive detection of inertial fusion capsule by X-ray phase contrast imaging.
