摘要

摘要: 本文给出一种氚钛厚靶氘氚反应加速器中子源的中子产额、能谱和角分布的计算方法，并开发了相应的计算模拟程序。用自行开发的计算程序计算了入射氘束流能量低于1.0 MeV时加速器中子源的中子产额、能谱和角分布，给出了氚钛厚靶的一些典型计算结果，并对结果的可靠性进行分析。

Abstract: A mathematical method and a computer program were developed to calculate the yield, energy spectrum and angular distribution of neutrons from the T(d,n)⁴He reaction in a thick tritium-titanium (TiT_x) target for incident deuteron beam energies lower than 1.0 MeV. Some calculated results using this method are presented, including integrated neutron yields, neutron energy spectra and angular distributions. The reliability of the results was analyzed.
