Development of new scintillator materials with vacuum ultraviolet emission

本研究的主要目标是开发具有VUV辐射(小于200 nm)的新型闪烁体材料。对以下主题进行了深入的研究。1.真空紫外闪烁体的高质量定形晶体生长2.以气体计数器为探测器的真空紫外闪烁体的辐射响应测试3.2.利用上述探测器进行二维辐射测绘，确定了Nd：LaF_3、Nd：LuLiF_4和Nd：LuF_3单晶的生长工艺。此外，所有探测器都获得了α射线和X射线信号以及二维图像。

In this study, main target is to develop new scintillator materials with VUV emission (shorter than 200nm). The following topics were intensively investigated. 1. High quality and shaped crystal growth of VUV scintillator 2. Test of radiation response using VUV scintillator with gas counter as detector 3. 2dimensional radiation mapping using above mentioned detector The bulk crystal growth technology of Nd:LaF_3、Nd:LuLiF_4 and Nd:LuF_3 single crystal is confirmed. In addition, Alpha-ray and X-ray signal and 2 dimensional image were obrained from all the detectors.
