| Outline of Final Research Achievements |
The range of X-ray applications especially in space science is still far from its potential because we currently only have small choices of practical X-ray optics. We thus focused on the development of an unprecedented optical element based on X-ray translation by Berry’s phase. This effect was recently discovered in the field of synchrotron science, and has been expected to realize a large change of a beam trajectory with no change of wave-front direction, yielding a parallel shift of an optical axis that cannot be achieved using an existing optical element based on reflection/refraction in X-rays. Our study here shows a new aspect of Berry’s phase, and successfully developed such an X-ray waveguide that should be a great seed for opening up a frontier of future high-energy experiments.
