| Outline of Final Research Achievements |
We experimentally verified the theoretical prediction of an anomalous x-ray translation of x-ray wave packet inside deformed crystal. In this research project, we applied the phenomenon to expand the research of x-ray optics. First, we proved that the exit beam is parallel to the incident beam with the similar angular low divergence. Second, we provided a high frequency temporal modulation on the crystal lattice deformation to see if the anomalous x-ray translation can follow the modulation. Experimentally the anomalous translation followed a fast modulation of 800 kHz. Furthermore, the exit beam from the crystal was scanned with the speed of 80 meter/s, due to the shrinkage and expansion of amount of translation. The fast scan speed of the output beam, 80 m/s, and the large stroke, 100 micrometers, indicate a new method of ultra-fast scanning of the x-ray beam which is difficult to achieve by scanning the specimens in the traditional way.
