强流氘氚聚变中子源HINEG设计研究

摘要

The R&D of HINEG (High Intensity D-T Fusion Neutron Generator ) includes two phases:HINEG-Ⅰ and HINEG-Ⅱ.HINEG-Ⅰ is designed to generate both the steady beam and pulsed beam,and have successfully produced a D-T fusion neutron yield of up to 1.1×1012 n/s. HINEG-Ⅱ aims at a high neutron yield of 101 4~1015 n/s neutrons via high speed rotating tritium target system and high intensity ion source. HINEG can be used for research of nuclear technology and safety including the validation of neutronics method and software, radiation shielding and protection, mechanism of materials activation and radiation damage as well as neutronics performance of components. Its application can also be extended to nuclear medicine, radiotherapy,neutron imaging and other nuclear technology applications. This paper introduces the scenario of design and progress in R&D of key technology of HINEG.%强流氘氚聚变中子源 HINEG (High Intensity D-T Fusion Neutron Generator)研发分两期：HINEG-Ⅰ为直流脉冲双模式，已成功产生中子强度1.1×1012 n/s的氘氚聚变中子，并实现连续稳定运行；HINEG-Ⅱ中子强度设计指标为1014~1015 n/s 量级，重点突破强流离子源和高载热氚靶技术. HINEG中子源可开展中子学方法程序与核数据、辐射屏蔽与防护、材料活化与辐照损伤机理和部件中子学性能等核能与核安全研究，同时也可在核医学与放射治疗、中子照相等领域拓展核技术应用研究.本文简要介绍 HINEG总体设计方案与关键技术研究进展.
