Abstract

The operating principle of two automated systems for real-time registration of the fluence of neutrons with energies higher than 0.1 MeV is considered. The first system is based on recording the neutron flux density using fission chambers with threshold radiators. The second is based on using silicon transistors as detectors and allowing for the dependence of their current amplification factor on the neutron fluence.

实时记录能量大于0.1 MeV的中子注量的自动化系统，用于辐射强度测试

摘要

考虑了两个自动系统的工作原理，该系统用于实时记录能量高于0.1 MeV的中子的注量。第一个系统是基于使用具有阈值辐射器的裂变室记录中子通量密度的。第二种是基于使用硅晶体管作为检测器，并允许其电流放大系数与中子注量有关。
