摘要
固体核径迹探测器已在电离辐射测量领域得到了广泛的应用,深入研究在固体核径迹探测器上形成径迹的形态信息(如长短轴、面积、深度分布等),有望可同时获得入射粒子的种类、能量和入射角度等重要参数,这对剂量学的准确评估至关重要。本文通过文献调研,归纳总结了固体探测器上径迹的形成原理以及仿真径迹蚀刻过程的研究进展,并对今后的研究工作做了部分展望。
Solid-state nuclear track detectors have been widely used in the field of ionizing radiation measurements.It is expected that important parameters such as the type,energy and incidence angle of the incident particles could be achieved throughout indepth studies on the shape information(such as length of major/minor axis,area,depth distribution,etc.)of the track formed on the solid nuclear track detector,and it is known that the parameters are critical for accurate dose assessment.Through the literature research,this paper summarizes the formation principle of the track on the solid detector and the research progress in the simulation of track etching process,and makes some prospects for the future research work.
