摘要

为了确定非圆截面托卡马克等离子体中MHD扰动的极向模数m,分析了几种局部磁探头实验信号处理方法的适用性。这些方法是二维傅里叶变换法、-希尔伯特变换法、奇异值分解法和相矩阵法。在T-15MD托卡马克真空容器的d型截面条件下,应用了上述方法。他们在确定局部磁探头合成信号和实验信号的MHD扰动的极向波数方面取得了良好的结果。对局部磁探头实验数据的处理结果与T - 15MD托卡马克软x射线诊断数据吻合较好。

Methods for Processing Signals of Magnetic Probes at the T-15MD Tokamak

Methods for Processing Signals of Magnetic Probes at the T-15MD Tokamak

The applicability of several methods for processing experimental signals of local magnetic probes is analyzed for the purpose of determining the poloidal mode number m of MHD perturbations in plasma of tokamak with noncircular cross-section. These methods are the two-dimensional Fourier transform, the -Hilbert transform method, the method of singular value decomposition, and the method of phase matrices. The methods listed were applied under conditions of the D-shaped cross-section of the T-15MD tokamak vacuum vessel. They showed good results in determining the poloidal wave numbers of MHD perturbations for both synthetic and experimental signals of local magnetic probes. The results of processing the experimental data from local magnetic probes were in good agreement with the data of soft X-ray diagnostics of the T‑15MD tokamak.

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.
