Measurements of detector response matrices, derived from time-of-flight, were made at the fast neutron facility at iThemba LABS, South Africa, with neutrons with energies between 10 - 65 MeV for: a traditional BC-501A organic liquid scintillator detector with photomultiplier tube and analogue pulse processing and acquisition; and a modern system comprised of an EJ-276 plastic scintillator, silicon photomultiplier and digital pulse processing and acquisition. The detector response matrices were validated by unfolding neutron energy spectra from measured light output spectra, and compared to the associated energy spectra derived from time-of-flight. Both detector systems demonstrated good agreement between the energy spectra derived from time-of-flight, which is promising for fast neutron spectroscopy with organic scintillators in environments outside of the laboratory.
