摘要：

Development of the plastic scintillator with neutron sensitivity from thermal to multi-MeV and pulse shape discrimination(PSD) has been demonstrated. Incorporation of B-10-containing compounds into the plastic scintillator with PSD capability leads to detector improvement in regard to neutron detection efficiency while preserving the discrimination between neutrons and gamma-rays. Effects of boron loading on scintillation and pulse shape discrimination properties are discussed. A PSD figure-of-merit value of 1.4 +/- 0.03 has been achieved for events in a thermal neutron energy domain, 50-100keV(ee), for PSD plastic loaded with 5 wt.% of m-carborane. (C) 2014 Elsevier B.V.
