中子参考辐射场是中子计量不可缺少的条件。它主要用于确定各种中子测量仪表的能量响应特性。 本工作按ISO8529-1的要求,利用SSDH-2型串列加速器,加速不同能量的质子和氘打到靶上,通过~7Li(P,n)~7Be,D(d,n)~3He和T(d,n)~4He核反应产生从100keV～19MeV的单能快中子。利用己研制的中子注量测量标准装置,准确测量某一点的中子注量,同时仔细研究不同核反应、不同位置散射中子的贡献,即可准确进行各种中子测量仪表响应的校准和能量响应的研究。
The neutron reference radiation field is an indispensable condition for neutron measurement. It is mainly used to determine the energy response characteristics of various neutron measuring instruments. According to the requirement of ISO8529-1, this work uses the SSDH-2 tandem accelerator to accelerate protons and deuterium of different energies to hit the target, The nuclear reaction of T (d, n) ~ 4He produces monoenergetic fast neutrons from 100 keV to 19 MeV. The neutron fluence measurement standard device has been used to accurately measure the neutron fluence at a certain point. At the same time, careful study of the contributions of different neutron reactors and scattering neutrons at different positions can accurately calibrate the response of various neutron measuring instruments and Research on energy response.
