THE RESPONSE MATRIX OF LIQUID SCINTTLLATOR ST-451 FOR FAST NEUTRON

摘要: 本文在给出了较好的物理过程描述和实验结果后,应用蒙特卡罗方法,计算了快中子入射到ST-451液体闪烁体中产生的反冲质子响应矩阵。给出了 0.25—30 MeV范围内(间隔 0.25或0.5 MeV的响应矩阵和中子探测器效率。并且可以很方便地扩展到能区 0.25—200 MeV范围。

Abstract: The rccoil proton response matrix of the liquid scintillator ST-451 for fastneutron is calculated using Monte Carlo method. The response matrix and neutrondetection efficiency are given in the energy range 0--30 MeV in step 0.25 MeV of0.5 MeV. It call be extended conveniently to energy 200 MeV. The experimentalresult is given for comparison.
