We developed a hybrid fast neutron spectrometer composed of three position-sensitive proportional counters and two surface barrier silicon semiconductor detectors. The hybrid spectrometer can measure energy and recoil angle of a recoil proton simultaneously. The spectrometer successfully gave a neutron spectrum with 1.7% energy resolution for a monoenergetic neutron (5.0MeV) beam.
