Development of weak focusing optical devise for synchrotron radiation X-rays

在传输装置中工作的x射线光学装置对于在现有同步辐射光束线的样品位置增加光子通量密度而尽可能少地重建是可取的。这项研究旨在开发这种新的x射线光学装置。设计、制作了原型器件，并对其光学性能进行了测试。获得了3.1的光子通量密度增益。该装置可用于x射线吸收精细结构光谱学、粉末衍射、小角度散射等不需要微聚焦的实验中改善光束线。

An X-ray optical device that operates in a transmission arrangement is preferable for increasing the photon flux density at a sample position of existing synchrotron radiation beamlines with as little reconstruction as possible. The study aimed to develop that new X-ray optical devise. The prototype device was designed, fabricated and the optical performances were measured. A photon flux density gain of 3.1 was achieved. The present optical device can be used to improve beamlines for experiments that do not require microfocusing such as X-ray absorption fine structure spectroscopy, powder diffraction, and small-angle scattering experiments.
