Research Abstract

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.
