国防核数据测量部产额组目前已完成14MeV中子诱发232Th裂变产额的实验测量及数据分析,得到了质量分布。采用232Th金属样品,核素32Th,丰度100%,质量约1g,直径22mm。样品使用纯铝箔包裹,以阻挡裂变碎片的逃逸。样品辐照在中国原子能科学研究院的高压倍加器上进行,靶片紧贴在靶管
At present, the output group of the national defense nuclear data measurement department has completed the experimental measurement and data analysis of the fission yield of 232Th induced by 14 MeV neutrons, and the mass distribution has been obtained. Using 232Th metal samples, nuclides 32Th, abundance of 100%, the quality of about 1g, a diameter of 22mm. Samples were wrapped with pure aluminum foil to stop the escape of fission fragments. The sample irradiation was carried out on the high-voltage doubler of China Institute of Atomic Energy, the target was close to the target tube
