论文摘要
抛物线单毛细血管X射线透镜（PMXRL）旨在有效地将实验室X射线源限制为平行梁。方形铅封锁器（SSLO）用于阻止PMXRL中的直接X射线。为了设计PMXRL，我们使用Python模拟镜头的圆锥参数（P = 0.001 mm），然后使用图纸计算机绘制相应的镜头（P = 0.000939 mm），总长度为60.8 mm。我们将SSLO放置在镜头入口进行光学测试。结果表明，受控的外传束的差异在15-45 mm的镜头出口范围内的差异小于0.4 mrad，在X射线成像方法中，镜头出口的距离具有出色的光学性能。设计细节在本文中报告。
A parabolic monocapillary X-ray lens (PMXRL) is designed to effectively constrain a laboratory point X-ray source into a parallel beam. A square-shaped lead occluder (SSLO) is used to block direct X-rays in the PMXRL. To design the PMXRL, we use Python to simulate the conic parameter (p = 0.001 mm) of the lens and then use a drawing machine to draw a corresponding lens (p = 0.000939 mm) with a total length of 60.8 mm. We place the SSLO at the lens inlet for optical testing. The results show that the controlled outgoing beam has a divergence of less than 0.4 mrad in the range of 15-45 mm of the lens outlet, which achieves excellent optical performance in X-ray imaging methodology. The design details are reported in this paper.
