Abstract

The possibilities of using active neutral particle diagnostics for measuring local ion temperatures and isotopic ratio of deuterium-tritium plasma at the tokamak with reactor technologies are considered. Options for positioning the neutral particle analyzer relative to the diagnostic injector are presented. The fluxes of deuterium and tritium atoms escaping out of plasma were simulated in a wide range of plasma densities and temperatures. It is shown that the neutral particle analyzer active diagnostics will make it possible to measure the plasma parameters mentioned with the spatial and time resolutions of ~14 cm and ~0.01–0.1 s, respectively.

在 TRT 设施使用主动中性粒子诊断的可能性

摘要考虑了利用反应堆技术在托卡马克测量局部离子温度和氘氚等离子体同位素比的可能性。介绍了中性粒子分析仪相对于诊断注入器的定位方案。模拟了在各种等离子体密度和温度下从等离子体中逸出的氘原子和氚原子的通量。结果表明，中性粒子分析仪主动诊断可以测量上述等离子体参数，空间和时间分辨率分别为~14 厘米和~0.01-0.1 秒。

期刊介绍： Plasma Physics Reports is a peer reviewed journal devoted to plasma physics. The journal covers the following topics: high-temperature plasma physics related to the problem of controlled nuclear fusion based on magnetic and inertial confinement; physics of cosmic plasma, including magnetosphere plasma, sun and stellar plasma, etc.; gas discharge plasma and plasma generated by laser and particle beams. The journal also publishes papers on such related topics as plasma electronics, generation of radiation in plasma, and plasma diagnostics. As well as other original communications, the journal publishes topical reviews and conference proceedings.
