Research on the Accelerator Neutron Source Characteristics Based on 9Be(d, xn) Reaction with Thick Target in the Low and Medium Energy Range

  • 摘要: 利用PHITS程序评价计算了厚靶9Be(d, xn)反应加速器中子源的能谱和角分布数据,重点讨论了JQMD、INCL和INCL/DWBA三种核反应物理模型计算厚靶9Be(d, xn)反应中子辐射场分布的适用性。研究结果显示,基于INCL/DWBA耦合模型的PHITS程序计算所得到的厚靶9Be(d, xn)反应中子能谱和角分布数据能够较好地与实验数据符合,可以为厚靶9Be(d, xn)反应中子源特性研究及应用提供较为准确的中子辐射场数据。此外,设计了水冷大面积旋转铍靶的方案,并在5~25 MeV/5 mA入射氘能量下条件下,开展了靶面温度模拟研究,结果显示,靶面最高温度可控制在100 ºC以下。

     

    Abstract: In this paper, the energy spectrum and angular distribution data of neutron source of 9Be (d, xn) reaction accelerator with thick target are evaluated and calculated by using PHITS program. The applicability of JQMD, INCL and INCL/DWBA nuclear reaction physical models to calculate the neutron radiation field distribution of 9Be (d, xn) reaction with thick target is discussed. The results show that the energy spectrum and angular distribution data of the thick target 9Be(d, xn) reaction calculated by the PHITS program based on the INCL/DWBA nuclear reaction physical model are in good agreement with the experimental data, and can provide more accurate neutron radiation field data for the study and application of the characteristics of 9Be (d, xn) reaction neutron source with thick target. In addition, the scheme of water-cooled large-area rotating beryllium target is designed, and the simulation study of target surface temperature is carried out under the condition of 5~25 MeV/5 mA incident deuterium energy. The results show that the maximum temperature of target surface can be controlled below 100 ºC.
