The Hard X‐ray Nanoprobe beamline, I14, at Diamond Light Source is a new facility for nanoscale microscopy. The beamline was designed with an emphasis on multi‐modal analysis, providing elemental mapping, speciation mapping by XANES, structural phase mapping using nano‐XRD and imaging through differential phase contrast and ptychography. The 185 m‐long beamline operates over a 5 keV to 23 keV energy range providing a ≤50 nm beam size for routine user experiments and a flexible scanning system allowing fast acquisition. The beamline achieves robust and stable operation by imaging the source in the vertical direction and implementing horizontally deflecting primary optics and an overfilled secondary source in the horizontal direction. This paper describes the design considerations, optical layout, aspects of the hardware engineering and scanning system in operation as well as some examples illustrating the beamline performance.

钻石光源的硬 X 射线纳米探针光束线

Diamond Light Source 的硬 X 射线纳米探针光束线 I14 是纳米级显微镜的新设施。光束线的设计重点是多模态分析，提供元素映射、XANES 形态映射、使用纳米 XRD 的结构相映射以及通过微分相衬和叠层成像的成像。185 m 长的光束线在 5 keV 至 23 keV 能量范围内运行，为常规用户实验提供 ≤50 nm 的光束尺寸，并提供灵活的扫描系统，允许快速采集。光束线通过在垂直方向上对源进行成像并在水平方向上实现水平偏转初级光学器件和溢出的次级源来实现稳健且稳定的操作。本文介绍了设计注意事项、光学布局、硬件工程和运行中的扫描系统的各个方面，以及说明光束线性能的一些示例。
