摘要：

The CATRiNA deuterated neutron detector array at Florida State University consists of 16 2 '' x 2 '' and 16 4 '' x 2 '' EJ-315 detectors with characteristic light output and pulse-shape discrimination capabilities. The unique properties of the detectors, in part due to the anisotropic nature of (d,n) scattering, are used to extract the energy of neutrons via pulse-height spectrum unfolding. The unfolding method uses the light output and response matrix of the detectors to extract neutron energies, independent of the traditional time-of-flight (ToF) technique. Detailed response matrices of the CATRiNA detectors were measured at the Edwards Accelerator Laboratory at Ohio University via the Be-9(d,n) and Al-27(d,n) reactions. Full characterization of the detectors using digital electronics, as well as a description of the unfolding method are reported.
