摘　　要：为满足强流中子发生器14 MeV 中子的辐照实验要求,已建立了基本配套的中子注量测量装置和两个环境剂量监测站.在样品待辐照的近靶区,测量了中子能谱、中子和γ剂量的空间分布.n-γ辐射场参数的测量将为中子物理实验和加速器的安全运行提供有用数据.In order to satisfy the requirements of 14 MeV Neutron radiation experi-ment on intense neutron generator,we have set up a basic complete set of neutron fluxmonitors and two environmental monitoring stations of radiation.The neutron spectrum and the n-γspace distribution in the region nearby the targethave been measured,the environmental radiation dosimetry around the operation roomhas also been measured.This work supplies useful data for neutron physics experimentand the safe operation of the intense neutron generator.
