Abstract

Abstract

The simulations of dark-field imaging of high energy electron radiography show that the dark field imaging is distorted in the case of large angle selected. In order to eliminate distortion, an optimized scheme is proposed in this paper. The results of high Energy Electron Radiography (HEER) simulations by optimization show that the dark-field image has better areal density resolution when the thickness of aluminum target is less than 25 μm, and the spatial resolution of dark-field imaging is about several microns. In summary, dark-field imaging of high energy electron radiography is ideal to thin warm dense matter specimen diagnosis.
