초록

A novel phoswich detector was set up by employing LaCl3 + LiI:Eu single crystal scintillators and was characterized in detail for its performance with Am-Be, D-D, and D-T neutron sources. LaCl3 crystal shows transparency to the scintillation emission of LiI:Eu for light collection to photo multiplier tube (PMT). Thermal and fast neutrons were successfully discriminated by pulse shape discrimination (PSD) with high value of figure of merit of 5.5 due to significant difference of their scintillation kinetics.
