摘要
CeF3是新型快响应无机闪烁体,对近年国内研制的CeF3无机闪烁体的时间特性进行了研究,包括脉冲辐射诊断所关心的CeF3对快脉冲γ辐射源的时间响应,如上升时间、半高宽、脉冲后沿;同时推算并使用了用脉冲法获得晶体发光衰减常数的简单估算公式,获得的CeF3衰减常数值与国外研究同行其它测量方法得到的结果基本一致。
CeF3 is a newly fast time response inorganic scintillator , the time characteristics of which, developed in recent ountry in nearly year were studied in our works. The time characteristics are rise time ,FWHM time and fall time for fast pulse radiation source . As the same time ,we have calculated and used the formula of pulse method gain to the decay time constant of crystal shining , the decay time constant measured is the same to the results of foreign references .
