| Research Abstract |
The asymmetric and the geometrical effects on the radiator crystal for parametric X-ray radiation (PXR) were investigated using Si(111) planes. The results show that the PXR beam emitted from the wedge-shaped edge of the target crystal has high performance with respect to both of the intensity and the spatial coherence. The improvement allows the reduction of the measurement time for phase images in diffraction-enhanced imaging. It led the computed tomography experiment using the PXR source to the world first success.
