摘要
对国内最新研制出的LaCl3:Ce3+闪烁晶体时间特性进行了测试,用该种晶体尝试组建了正电子湮没寿命谱仪,时间分辨率达到了350ps。由于LaCl3:Ce3+探头在具有快速时间响应特性的同时还具有较高的能量分辨率,用该探头组建正电子湮没寿命谱仪将具有许多潜在的优势。
The timing properties of LaCl3：Ce^3＋ scintillation crystals, which were developed in China lately , have been tested. A positron annihilation lifetime spectrometer was constructed with these detectors. A time resolution of 350 ps was obtained. Besides the fast time response, the energy resolution of LaCl3 ：Ce^3＋ is also high, so there are many potential advantages of the positron annihilation lifetime spectrometer constructed with this kind of detectors.
