研究聚变反应堆中的等离子体物理需要一种测量由碰撞 α 粒子产生的高能 DT 中子尾的方法。核乳剂为快中子的检测提供了令人满意的性能，并使用三维跟踪信息测量它们的能量。然而，分析所需的时间构成了这种测量技术实施的瓶颈。最近，由于我们的开发，核乳剂的分析速度显着提高。在本报告中，我们建议使用最新的分析技术和方法验证，使用核乳剂进行 DT 燃烧等离子体诊断。此外，我们还讨论了改进核乳剂技术用于融合等离子体诊断的前景。
A method for the measurement of energetic DT neutron tails resulting from knock-on alpha particles is needed to study plasma physics in a fusion reactor. A nuclear emulsion offers satisfactory performance for the detection of fast neutrons and measures their energies using three-dimensional tracking information. However, the time required for analysis forms a bottleneck in the implementation of this measurement technique. Recently, the analysis speed of nuclear emulsion has dramatically increased because of our development. In this report, we propose the use of nuclear emulsion for DT burning plasma diagnostics using the latest analysis technology and the validation of the methodology. In addition, we discuss the prospects of improving nuclear emulsion technologies for fusion plasma diagnostics.
