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
