【 摘 要 】

MaRIE x-ray free electron laser (FEL) is envisioned to deliver a burst of closely spaced in time pulses for enabling the capability of studying the dynamic processes in a sample [1]. There is a large variety of materials of interest which dynamics will be studied. Most likely all these materials cannot be diagnosed using a single imaging technique. For example, techniques which can be applied to image polycrystalline metals will not be applicable to imaging amorphous materials due to lack of Brag refractions in such a media. On the other hand, amorphous media are not as dense as metals which allows one sampling them with a much softer radiation due to smaller scattering and absorption.
