Abstract
We have characterized the neutron and alpha light output response, and anisotropy of a 140 cm3 deuterated trans-stilbene (stilbene-d12) crystal of approximately. The neutron light output response was characterized in the 0.5 to 14.1 MeV energy range using a coincidence neutron scattering system, based on a D-T source. The light output response to alpha particles was characterized in the 5 to 6 MeV range using multiple alpha sources. The light output response to the two types of particles is explained well by a semi-empirical functional form based on the Birks' light-output model. The anisotropy of the stilbene-d12 was characterized from 0° to 360° in response to 14.1 MeV neutrons. The stilbene-d12 has a larger light emission when the beam direction is parallel to the b axis in the a-b crystal plane. The crystal used in this work was grown at Lawrence Livermore National Laboratory using a solution growth method.
