摘要
The combination of nuclear models with a Monte Carlo transportation code like MCNP, GEANT4 and FLUKA,nucleon meson transport codes (NMTC) are widely utilized for designing of Accelerator Driven Systems (ADS).However, the nuclear models embedded into transportation codes need to be validated by experimental measure-ments. A Neutron Time-of-Flight (NTOF) spectrometer, which is based on Heavy Ion Research Facility in Lanzhou(HIRFL), is designed for further investigations of reaction mechanisms and neutron productions of proton inducedspallation reactions related to the ADS project. The NTOF spectrometer is capable of measuring neutrons in awide energy and angular ranges. It consists of a beam pick-up detector and 10 individual neutron detection modules.The schematic view of the NTOF spectrometer is shown in Fig. 1.
