D-T中子照射铁球γ射线角通量谱测量

Measurement and Calculation of γ-ray Angular Flux Spectra of Iron Sphere Bombarded by D-T Neutrons

摘要: 用NE2 13探测器测量了R18 1cm× 10cm铁球在中心D T中子照射下 0°、19 4°、4 1 5°方向泄漏γ射线角通量谱, 用MCNP/4A程序与t 2、FENDL 2核数据库对实验进行了模拟计算, 并与实验结果进行了比较。采用t 2库的计算结果与实验符合较好。

Abstract: Angular flux spectra of leakage γ rays of an iron sphere bombarded by D T neutrons from its center are measured with a NE213 scintillation detector at 0°,19.4° and 41.5° with the normal of its surface. The measured results are compared with calculated results of MCNP/4A code with t 2 and FENDL 2 library. The calculated results with t 2 library coincide better with measured results.
