摘要
利用 X 射线点源研究了低角度扭曲边界的衍射行为。结果表明,当射线聚焦在晶体内部时,由于缺陷壁的位错结构,垂直发散可以大大减小,以至于该方向的焦点尺寸明显小于水平方向。这种情况可用于制造 X 射线光学元件。
Features of Spherical X-Ray Wave Diffraction by a Low Angle Twist Boundary Perpendicular to the Crystal Surface
An X-ray point source was used to examine the diffraction behavior of a low-angle twist boundary. It is shown that when radiation is focused inside a crystal, because of the dislocation structure of the defect wall, the vertical divergence can be reduced so much that the size of the focus in this direction is significantly smaller than in the horizontal direction. This circumstance can be used to create X-ray optical elements.
