【摘要】 用整体平行束X光透镜代替常规衍射仪的索拉狭缝和/或附加狭缝,入射和衍射X光强度可提高1.5―3.5倍,分辨率可达0.4°,可用于薄膜、粉末样品和离子束沉积样品的分析。将微会聚X光透镜应用于生物大分子衍射、高压X射线衍射、四圆X射线衍射3个不同的衍射领域,在相同X光源功率条件下,使用X光透镜后的衍射强度提高到原来的3―10倍,信噪比和分辨率有不同程度的改善。更多还原

【Abstract】 By using monolithic parallel beam X-ray lens instead of the attachment slits or Soller slits, the X-ray intensities both incident on and diffracted from the sample can be 1.5—3.5 times than the original and a resolution of 0.4°can be reached, thus the diffractional setup with X-ray lenses can be used to analyse thin film, powder and ion beam deposit samples. By using the slightly focusing X-ray lens in the macromolecular crystallography, high pressure and four circle X-ray diffractometers and at the same electric power supply, the diffracted intensities can be raised 3—10 times than the traditional diffractional equipment. In addition the signal to noise ratio and the resolution can be improved to a certain extent.更多还原
