摘要：
A novel spherically bent crystal analyzer was developed based on the X-ray Bragg diffraction theory to study and diagnose the distribution, stability and the shape of a plasma of pellet implosion in the Inertial Confinement Fusion (ICF). The key component of the crystal analyzer is a spherically bent α-quartz crystal with a radius of 143.3 mm. The spherically bent α-quartz crystal was used to carried out a monochromatic X-ray backlighting imaging experiment in the Research Center of Laser Fusion, China Academy of Engineering Physics(CAEP). The clear two-dimensional monochrome X-ray backlighting image of a chrome target was obtained on an imaging plane of 40 mm×30 mm. By analyzing the spectral information of a sagittal direction in the experiment, it is demonstrated that the spherically bent α-quartz crystal shows his spatial resolution to be 83.3 μm and it could be used for research of the monochromatic X-ray backlighting imaging.
