中子气泡探测器性能改进及初步检验

Performance Improvement and Preliminary Test on Neutron Bubble Detector

摘要: 对自制中子气泡探测器进行了改进。对改进后探测器的个人中子剂量响应以及重现性、批内一致性在国防科学技术工业委员会放射性计量一级站的中子仪表刻度实验室进行了检验。结果显示，探测器的重现性、剂量响应和批内一致性等主要特性有了大幅提高。

Abstract: The design of the neutron bubble detectors developed by our group was upgraded. The dose response, reproducibility, and in-batch consistency of the renovated detectors were tested in the Department of Radioactive Metrology, China Institute of Atomic Energy. The results indicate that these renovations have brought an important upgrade in overall performances of our bubble detectors.
