摘要
用六种阈能探测器Fe、Al、C2F4、Nb、Zr和Cu测量了D-T聚变中子在柱状组合材料上的高阈能活化反应率,讨论了实验结果。用MCNP/4B程序计算了实验装置上的活化反应率,并与实验结果进行比较。结果表明,除F活化反应率符合较好外,其余相差10％-30％。
High-threshold-energy activation reaction rates were measured in cylindric combined materials bombarded by D-T neutrons with 6 threshold-energy detectors Fe, Al, Nb, F, Zr and Cu. The experimental results are discussed. MCNP/4B code was used to calculate the activation reaction rates on the experimental device. The calculated results are compared with the experimental ones. It shows that the discrepancies are 10%-30% except for the F activation reaction rate.
