提出了一种利用聚乙烯薄膜和Si（Au）表面势垒探测器测量D-T中子能谱的质子反冲法。研究了一种将反冲质子能谱展开为中子能谱的迭代算法。利用MCNPX程序模拟单能中子的反冲质子能谱，得到了聚乙烯薄膜在0角和45角处的响应矩阵R。采用假设的D-T中子谱，用MCNPX程序模拟了聚乙烯薄膜在0角和45角处的反冲质子谱。基于响应矩阵R和0和45处的模拟反冲质子谱，利用迭代算法分别得到了展开中子谱。并与假设的中子谱进行了比较。结果表明，迭代算法可以将反冲质子能谱展开为中子能谱，用于反冲质子法测量D-T中子能谱。
A proton recoil method for measuring D-T neutron energy spectra using polyethylene lm and a Si(Au) surface barrier detector is presented. An iteration algorithm for unfolding the recoil proton energy spectrum to the neutron energy spectrum is investigated. The response matrices R of the polyethylene lm at angles of 0 and 45 were obtained by simulating the recoil proton energy spectra from mono-energetic neutrons using the MCNPX code. With an assumed D-T neutron spectrum, the recoil proton spectra from the polyethylene lm at angles of 0 and 45 were also simulated using the MCNPX code. Based on the response matrices R and the simulated recoil proton spectra at 0 and 45, the respective unfolded neutron spectra were obtained using the iteration algorithm,.and compared with the assumed neutron spectrum. The results show that the iteration algorithm method can be applied to unfold the recoil proton energy spectrum to the neutron energy spectrum for D-T neutron energy spectra measurement using the recoil proton method.
