Abstract

The instrumental effects related to the use of a polycapillary x-ray lens as primary beam collimator are here studied and the features observed in the measurements modelled via Monte-Carlo ray-tracing. Comparison with existing procedures is presented and experimental evidence of the accuracy improvements due to the use of a correction algorithm is shown.

摘要

本文研究了将多毛细管X射线透镜用作初级光束准直器所产生的仪器效应，并通过蒙特卡罗光线追踪对测量中观察到的特征进行建模。文中给出了与现有程序的比较，并展示了使用校正算法后精度提高的实验证据。
