| 中文摘要: |
| 基于数据采集卡采用全脉冲获取方法对BaF2闪烁体探测器探测α粒子及γ射线的核脉冲波形进行了研究，通过计算全波形的面积提取了核脉冲信号的能量信息，构建了能谱.应用脉冲形状甄别方法对α粒子和γ射线进行了鉴别研究，根据脉冲信号的快/慢成分比的差别清楚地将α粒子从γ射线中鉴别开来.剔除了BaF2闪烁体探测器中固有226Ra及其子体222Rn、218Po、214Po本底的干扰. |
| 英文摘要: |
| Signals of α particle and γ ray from the BaF2 detectors were acquired using the Flash ADC.The energy spectrum were obtained by direct integrating the pulse shape.Differences of the pulse shape were studied by off line data analysis.α particles and the γ rays have been identified by the pulse shape discrimination.The Ra background has been eliminated. |
