摘要

为实现伴随粒子中子管研究中的小靶点表征，设计了一种基于YAG∶Ce材料的模块化荧光靶体，给出了一种靶点实时监视与测量的方法。利用该方法实现了伴随粒子中子管最小4 mm直径靶点的实验工作。研究中在可更换的荧光靶面上经过激光雕刻阵列化后，能够分辨毫米级甚至亚毫米级的靶点大小。经过长时间高能离子束轰击后的YAG∶Ce材料靶面能够持续发光，未见性能下降，证明YAG∶Ce材料具有良好的耐辐照性能。

Abstract

In order to realize the characterization of smaller beam spot in the research of associated particle

a kind of modular fluorescence target by using YAG:Ce

was designed

and a kind of real-time monitor and measurement approach was presented. By using this approach

the maximum diameter of the beam spot reaches 4 mm. After engraving into array form by laser in the replaceable fluorescence target surface

the monitor and measurement accuracy of the beam spot size is millimeter level

even is sub millimeter level. After bombarding by high energy ion beam for a long time

YAG:Ce

can keep on shining without performance degradation

which means YAG:Ce

has good radiation-resistant performance.
