摘要

硬X射线纳米探针光束线BL13U是上海同步辐射中心的一个二期光束线项目。该光束线旨在实现从 50 纳米到 10 纳米的高空间分辨率综合实验。光束线的 X 射线能量范围为 5-25 keV，可探测元素周期表中的大多数元素。为满足高能量分辨率或高光子通量的实验要求，分别设计了两种运行模式。X 射线纳米荧光、纳米衍射和相干衍射成像是 BL13U 的主要实验技术。本文介绍了光束线光学系统、终端站配置、正在开发的实验方法以及初步测试结果。这一全面概述旨在让人们清楚地了解光束线的能力和潜在应用。

The hard X-ray nanoprobe beamline at the SSRF

The hard X-ray nanoprobe beamline BL13U is a phase-II beamline project at the Shanghai Synchrotron Radiation Facility. The beamline aims to enable comprehensive experiments at high spatial resolutions ranging from 50 to 10 nm. The X-ray energy range of the beamline, 5–25 keV, can detect most elements in the periodic table. Two operating modes were designed to accommodate the experimental requirements of high-energy resolution or high photon flux, respectively. X-ray nanofluorescence, nanodiffraction, and coherent diffraction imaging are developed as the main experimental techniques for BL13U. This paper describes the beamline optics, end station configurations, experimental methods under development, and preliminary test results. This comprehensive overview aims to provide a clear understanding of the beamline capabilities and potential applications.
