A new diffraction beamline for materials science has been built at the Canadian Light Source synchrotron. The X‐ray source is an in‐vacuum wiggler with a 2.5 T peak magnetic field at 5.2 mm gap. The optical configuration includes a toroidal mirror, a single side‐bounce Bragg monochromator, and a cylindrical mirror, producing a sub‐150 µm vertical × 500 µm horizontal focused beam with a photon energy range of 7–22 keV and a flux of 10¹² photons per second at the sample position. Three endstations are currently open to general users, and the techniques available include high‐resolution powder diffraction, small molecule crystallography, X‐ray reflectivity, in situ rapid thermal annealing, and SAXS/WAXS. The beamline design parameters, calculated and measured performance, and initial experimental results are presented to demonstrate the capabilities for materials science.

用于加拿大光源材料科学的较低能量衍射和散射侧反射光束线

加拿大光源同步加速器已经建立了一种新的用于材料科学的衍射光束线。X射线源是一个真空内摆动器，在5.2 mm的间隙处具有2.5 T的峰值磁场。光学配置包括一个环形反射镜，一个单侧向反射布拉格布拉格单色仪和一个圆柱镜，可产生小于150微米的垂直×500微米的水平聚焦光束，光子能量范围为7-22 keV，通量为10 ¹²样品位置每秒的光子数。目前向普通用户开放了三个终端站，可用的技术包括高分辨率粉末衍射，小分子晶体学，X射线反射率，原位快速热退火和SAXS / WAXS。提出了束线设计参数，计算和测量的性能以及初步的实验结果，以证明材料科学的能力。
