介绍了一种基于单个EJ299-33型塑料闪烁体(直径5 cm×5 cm)的中子谱仪。脉冲形状辨别的数字实现用于将与中子有关的事件与与伽马射线有关的事件分开。使用纳秒脉冲中子束进行的测量被用来产生探测器对能量范围为10-100 MeV的中子的响应函数。这些线型被用来测试光谱仪通过展开脉冲高度谱来产生中子能谱的能力，以用于具有任何类型时间结构的中子场。并与用EJ301液体闪烁体建造的类似光谱仪的测量结果进行了比较。
A neutron spectrometer based on a single EJ299-33 plastic scintillator (5 cm diameter × 5 cm) is described. A digital implementation of pulse shape discrimination is used to separate events associated with neutrons from those associated with gamma-rays. Measurements made using a ns-pulsed neutron beam are used to produce response functions of the detector for neutrons over the energy range 10 - 100 MeV. These lineshapes are used to test the capability of the spectrometer to produce neutron energy spectra, via the unfolding of pulse height spectra, for use in neutron fields having any type of time structure. The results are compared with those from a similar spectrometer constructed from EJ301 liquid scintillator.
