摘要

由于等离子体的复杂性，解释托卡马克中的实验诊断数据（考虑非理想效应）具有挑战性。为了应对这一挑战，我们建立了一个通用合成诊断（GSD）平台，用于微波成像反射仪（MIR）和电子回旋发射成像（ECEI）。该平台利用等离子体剖面作为输入，并结合有限差分时域（FDTD）、射线追踪和辐射传递方程来计算等离子体自发辐射和外部电磁场在等离子体中的传播。为了验证 GSD 平台中每个核心模块的准确性，对经典案例进行了基准测试。最后，该平台再现了典型电子温度分布的二维成像，与给出的真实实验数据一致。该平台还具有扩展到三维电磁场模拟和其他微波诊断（如交叉极化散射）的潜力。

A synthetic diagnostics platform for microwave imaging diagnostics in tokamaks

Interpreting experimental diagnostics data in tokamaks, which accounts for non-ideal effects, is challenging due to the complexity of plasmas. To address this challenge, a general synthetic diagnostics (GSD) platform that serves for microwave imaging reflectometer (MIR) and electron cyclotron emission imaging (ECEI) has been established. This platform utilizes plasma profiles as input, and it incorporates finite difference time domain (FDTD), ray-tracing and radiative transfer equation to calculate the propagation of plasma spontaneous radiation and external electromagnetic field in plasmas. Benchmarks of classic cases have been conducted to verify the accuracy of every core module in GSD platform. Finally, a 2D imaging of a typical electron temperature distribution is reproduced by this platform and is consistent with the given real experimental data. This platform also has potential to be extended to 3D electromagnetic field simulations and to other microwave diagnostics such as cross-polarization scattering.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
