The Advanced Photon Source 1‐ID beamline, operating in the 40–140 keV X‐ray energy range, has successfully employed continuously tunable saw‐tooth refractive lenses to routinely deliver beams focused in both one and two dimensions to experiments for over 15 years. The practical experience of implementing such lenses, made of silicon and aluminium, is presented, including their properties, control, alignment, and diagnostic methods, achieving ∼1 µm focusing (vertically). Ongoing development and prospects towards submicrometre focusing at these high energies are also mentioned.

使用锯齿形折射透镜在高能X射线束线上聚焦。

在40–140 keV X射线能量范围内运行的高级光子源1-ID光束线已成功采用连续可调的锯齿形折射透镜，以常规方式将聚焦在一维和二维方向上的光束传递到实验中超过15年。介绍了实现由硅和铝制成的这种透镜的实践经验，包括其性能，控制，对准和诊断方法，可实现约1 µm（垂直）聚焦。还提到了以这些高能量为重点的亚微米的正在进行的开发和前景。
