D-T中子照射下含硼聚乙烯球泄漏γ能谱测量

Measurement of Leakage Gamma Spectra in Boron-containing-PE Spheres by D-T Neutron

    摘要
  • 摘要: 为了更清楚地了解含硼聚乙烯的屏蔽性能,用反冲电子法测量了D T中子照射下的不同B4C含量的聚乙烯球的泄漏γ能谱,并用MCNP/4A程序和ENDF/BⅤ库数据进行模拟计算。实验测量值和计算值在误差范围内符合得较好。

     

    Abstract: The leakage gamma spectra from PE spheres with different percentage of B_4C and different thickness irradiated by D-T neutron were measured. The leakage gamma spectra were calculated using MCNP/4A code with ENDF/B-Ⅴ database. Comparing with the experiment, they have good consistency within the error range.
