Abstract
The paper discusses the possibility of using the Doppler backscattering (DBS) diagnostic to aid the Tokamak with Reactor Technologies (TRT) with its mission, and also offers ways of installing it in TRT, including the possible technical characteristics of the system. One of the most important advantages of DBS implementation is the ability to investigate various areas of plasma. This requires selecting an appropriate range of probing frequencies to match the scenarios and density profiles expected in TRT. Aspects and advantages of different ways of implementing DBS in the tokamak are discussed. Possible hardware, design and arrangement of the antenna system are presented. There are also system limitations that need to be considered specifically for TRT. The propositions for DBS on TRT are supported by calculations of ray tracing and diagnostic resolution. The wave number values of plasma fluctuations that the system could detect are also estimated.
摘要 本文讨论了利用多普勒反向散射（DBS）诊断技术协助托卡马克反应堆技术（TRT）完成其任务的可能性，并提出了在 TRT 中安装该诊断技术的方法，包括该系统可能具有的技术特点。实施 DBS 的最重要优势之一是能够调查等离子体的各个领域。这就需要选择适当的探测频率范围，以匹配 TRT 中预期的情景和密度剖面。本文讨论了在托卡马克中实施 DBS 的不同方法的各个方面和优势。还介绍了天线系统的可能硬件、设计和布置。此外，还需要特别考虑 TRT 的系统限制。通过射线追踪和诊断分辨率的计算，支持在 TRT 上使用 DBS 的提议。还估算了该系统可以探测到的等离子体波动的波数值。
