摘要
为进一步降低采购成本,提升设备的维护性,打破国外垄断,通过优化晶体的封装耦合方式提升国产大尺寸NaI(Tl)探测器的探测性能。分别针对搭载国产和进口大尺寸NaI(Tl)探测器的全身计数器系统开展分辨率、短期稳定性等实验对比测试。实验结果表明:通过优化晶体的封装耦合方式制造的国产大尺寸NaI(Tl)探测器的能量分辨率小于8%,峰位变化在±1%峰位以内,能够满足测量要求。
In order to further reduce the procurement cost,improve the maintainability of the equipment and break the monopoly of foreign countries,the detection performance of the domestic large-size NaI(Tl)detector is improved by optimizing the packaging coupling mode of the crystal.The resolution and short-term stability of the whole body counter system equipped with domestic and imported large-size NaI(Tl)detectors were tested and compared.The experimental results show that the energy resolution of the homemade large-size NaI(Tl)detector is less than 8%,and the peak position variation is within±1%,which can meet the measurement requirements.
