摘要/Abstract

摘要： 给出一种计算氘钛厚靶D(d,n)³He反应加速器中子源的产额、能谱和角分布的方法,并发展了一个计算机模拟程序,程序能够计算氘束流能量小于1.0 MeV的中子源的产额、能谱和角分布.计算时使用推荐的D(d,n)³He反应截面数据和来自SRIM-2003程序的氘在氘钛靶中的阻止本领数据.给出一些典型计算结果,包括中子积分产额、中子能谱和角分布.

关键词: D(d, n)³He反应, TiDx厚靶, 中子产额, 中子能谱, 中子角分布

Abstract: A mathematical model and a program are developed to calculate neutron yields, energy spectrum and angular distribution of D (d, n)³He reaction in a thick deuterium-titanium (TiD_x) target as incident deuteron energy lower than 1.0 MeV. D(d, n)³He reaction cross section from nuclear data tables and stopping power derived with SRIM-2003 code are adopted in the calculatoin of neutron production of an accelerator-based D(d, n)³He reaction neutron source. Integrated neutron yields, neutron energy spectrums and angular distribution are obtained.

Key words: G(d,n)³He reaction, thick TiDx target, neutron yields, neutron energy spectrum, neutron angular distribution
