In order to overcome space limitations, a novel method is introduced to measure the focal point size of a sagittally bent Laue crystal monochromator by using a multi-hole array. Combined with ray-tracing measurements, the focal length and focused beam size were determined. Theoretical simulations and experiments were performed to demonstrate the feasibility of this method. The experimental results show that this method can provide a fast way of measuring the focusing characteristics of a sagittally bent Laue crystal monochromator.
为了克服空间限制，引入了一种新方法，即使用多孔阵列来测量矢状弯曲劳厄晶体单色仪的焦点尺寸。结合光线追迹测量，确定了焦距和聚焦光束尺寸。进行了理论模拟和实验以证明该方法的可行性。实验结果表明，该方法能够提供一种快速测量矢状弯曲劳厄晶体单色仪聚焦特性的途径。
