摘要/Abstract

摘要： 为了实现中子能谱的快速获取,准确测量中子辐射场的剂量率,设计了一款一体化多球中子能谱仪。该系统能进行中子能谱的在线测量,实时显示中子剂量率。谱仪在Am-Be参考辐射场进行了验证,测量能谱与标准谱符合较好,转换后剂量率测量值与真值偏差<±7%。

Abstract: In order to obtain neutron spectrum quickly and measure the dose rate of neutron radiation field accurately, an Bonner sphere spectrometer was designed. The system can measure neutron spectrum online and display neutron dose rate in real time. The spectrometer was verified in a Am-Be reference radiation field. The result was in good agreement with the standard spectrum, and the deviation between the measured dose rate and the true value after conversion was less than ±7%.

Key words: Neutron spectrum, Bonner sphere spectrometer, Neutron dose rate
