Chinese Abstract

建立了系列厚度爲3、6、11、16、21.8cm的鐵球基準裝置。用BC-50lA譜儀測量了D-T中子穿透鐵球伴生γ射線泄漏能譜,能量範圍爲0.5~5MeV。通過能譜分析,觀測到鐵球厚度對能譜有一定影響。利用MCNP4A程序和t-2、ENDF/B-V、ENDF/B-Ⅵ和FENDL-2等數據庫對實驗進行了模擬計算,並將計算結果與實驗結果進行了比較。γ射線能譜實驗誤差為4%~6%。

English Abstract

A benchmark of iron shell with a series of thickness of 3, 6, 11, 16 and 21.8cm was established. The leakage gamma-ray energy spectrum emitted by iron sphere from D-T neutron was measured using BC-501A spectrometer, the energy range was 0.5~5MeV. From the analysis of gamma-ray spectrum, the effect of iron shell's thickness on the spectra was found. The measured results are compared with that from calculated by using MCNP4A mode and t-2, ENDF/B-V, ENDF/B-Ⅵ and FENDL-2 data banks. The overall experimental error of gamma-ray spectrum is 4%~6%.
