活化法测量散裂靶中子能谱的实验验证
Experiment Verification of Measurement for Neutron Spectrum of Spallation Source by Activation Method
摘要
Abstract
The spectrum of spallation neutron source is of great influence on the multi‐plication factor and transmutation rate of ADS .It is show n that the spectra of spallation target neutron and fission neutron are similar in MeV region .In this paper ,the leakage neutron spectrum and neutron fluence rate of the critical assembly w ere measured by activation method with In ,Al ,Mg ,Ti ,Au ,Zn ,Ni ,Rh ,Fe and Co foils as activation foils .T he results show that the activation method can be used to measure the neutron spectrum in the spallation target neutron field .T he neutron fluence should be up to 5 × 1014 cm -2 in 5 h .The activation foils should be taken out in 1 h after irradiation .The measure order is according to the length of the half‐life .关键词
