摘要

核反应堆的安全运行、新一代反应堆设计以及核废料处理等需要精确的中子核数据。光中子源联用飞行时间谱(Time of Flight

TOF)测量是最精确的中子能量测量技术，在热中子和共振中子能区的截面测量中发挥了非常重要的作用。钍基熔盐堆(Thorium Molten Salt Reactor

TMSR)项目中15 MeV电子加速器驱动的光中子源装置(TMSR Photo-Neutron Source Phase 1

TPNS1)是专为钍-铀循环核数据测量设计和建造的，它位于中国科学院上海应用物理研究所嘉定园区内。第一阶段采用15 MeV电子直线加速器(LINAC)驱动，第二阶段拟建造电子能量约100 MeV (TPNS2)驱动的光中子源。前者建成后可提供飞行路径5 m、通量约104 n?s?1?cm?2的连续能量中子束（白光中子）及约1 MeV低能伽马射线，它们分别用于测量中子反应截面和伽马辐照研究，这是国内首台用于核数据测量的白光中子源。

Abstract

Background: Neutron evaluated data were needed by many researches

e.g.

the safety traffic of nuclear reactor

design of new generated reactor and treatment of nuclear waste. Purpose: The photo-neutron source driven by 15-MeV electrons LINAC in Thorium molten salt reactor (TMSR) program was designed for Th-U cycle nuclear data measurement. Methods: The photo-neutron source combined with time of flight (TOF) spectra is the most accurate method in neutron energy measurement

which plays a very important role in thermal and resonance neutron cross section measurement. Results: It locats in Jiading campus of Shanghai Institute of Applied Physics (SINAP). In the first phase

a 15-MeV electron LINAC will be manufactured

and then a more high energy about 100-MeV LINAC will be used for the photo-neutron source. Conclusion: The facility (phase 1) will supply the 5-m TOF path and white spectrum neutron with flux ~104 n?s?1?cm?2 and low energy gamma ray ~1 MeV

and it will be used in neutron cross section measurement and gamma irradiation study. This is the first white neutron source facility designed for TMSR nuclear data measurement. Abstract
