【摘要】 大、中型托卡马克在D-D和D-T运行条件下聚变中子能谱测量具有重要意义。论述了几种最新的聚变中子能谱仪,评估了各种聚变中子能谱仪的优势、适用的范围和技术方面的局限性,并对即将建成的HL-2A(中国环流器二号A)托卡马克的聚变中子的泄漏能谱测量以及研究聚中子在通过中子倍增剂过程中的能谱变化,在聚变中子能谱诊断方面提供了几种可供选择的技术方案。更多还原

【Abstract】 It is very important that spectrum measurement of D-D and D-T fusion neutron in large scale Tokamak. Severalnewest energy spectrometers of fusion neutron, and review their technical characters, applicable range, and limit of technologyare introduced. As a consequence, a new energy spectrometer which is suitable to HL—2A Tokamak for studying the multipli-cation of fusion neutron and the breeding of tritium fuel is design.更多还原
