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.

在传输排列中运行的X射线光学设备可优选，可在现有同步辐射梁线的样品位置上增加光子通量密度，并尽可能少地重建。该研究旨在开发新的X射线光学设计。设计，制造了原型设备，并测量了光学性能。实现了3.1的光子通量密度增益。目前的光学设备可用于改善不需要微焦点的实验的光束线，例如X射线吸收良好的结构光谱，粉末衍射和小角度散射实验。
