A NE230 deuterated liquid scintillator detector (25 mm diameter x 25 mm) has been used to investigate neutron energy spectra as a function of position in a water phantom under irradiation by a quasi-monoenergetic 64 MeV neutron beam. Neutron energy spectra are obtained from measurements of pulse height spectra by the NE230 detector using the Bayesian unfolding code MAXED. The experimentally measured energy spectra are compared with spectra calculated by Monte Carlo simulation using the code MCNPX.
一个NE230氘化液体闪烁探测器（直径25毫米×25毫米）被用于研究在准单能64兆电子伏中子束照射下，水模体中中子能谱随位置的变化。通过使用贝叶斯展开代码MAXED的NE230探测器对脉冲高度谱进行测量来获得中子能谱。将实验测量的能谱与使用代码MCNPX通过蒙特卡罗模拟计算的能谱进行比较。
