摘　　要：A Neutron Time-of-Flight(NTOF) spectrometer, based at the Heavy Ion Research Facility in Lanzhou(HIRFL) was developed for studies of neutron production of proton induced spallation reactions related to the ADS project. After the presentation of comparisons between calculated spallation neutron production doubledifferential cross sections and the available experimental data, a detailed description of the NTOF spectrometer is given. Test beam results show that the spectrometer works well and data analysis procedures are established.The comparisons of the test beam neutron spectra with those of GEANT4 simulations are presented.A Neutron Time-of-Flight（NTOF） spectrometer, based at the Heavy Ion Research Facility in Lanzhou（HIRFL） was developed for studies of neutron production of proton induced spallation reactions related to the ADS project.
