[en] A neutron time-of-flight spectrometer used for measurement of neutron differential cross sections in the U-150 accelerator is described. Schemes of experimental rooms, beam collimation and system of data collection in the CAMAC standard on-line with the SM-4 computer as well as neutron spectra from (p, n), (d, n) and (³He, n) reactions at 17.8, 13.6 and 23 MeV respectively are presented. Software is ensured in the MAKRO-11 language with a set of subprograms exercising realization of different operational modes of the sectrometer
