We have experimentally characterized the light-output response of a deuterated trans-stilbene (stilbene-d12) crystal to quasi-monoenergetic neutrons in the 0.8 to 4.4 MeV energy range. These data allowed us to perform neutron spectroscopy measurements of a DT 14.1 MeV source and a PuBe source by unfolding the impinging neutron spectrum from the measured light-output response. The stilbene-d12 outperforms a H-stilbene of similar size when comparing the shape of the unfolded spectra and the… Expand
