- Abstract
- The applicability of several signal processing methods is analyzed for local magnetic probes experimental data aimed at determining the poloidal mode number (m) of MHD perturbations in the plasma of a tokamak with a non-circular cross-section. These include two-dimensional Fourier decomposition, the Hilbert transform method, singular value decomposition, and the phase matrix method. These methods have been applied under the conditions of the D-shaped cross-section of the T-15MD vacuum chamber and have shown good results in determining the poloidal wave numbers of MHD perturbations for both synthetic and experimental local magnetic probes signals. The results of processing experimental data from local magnetic probes demonstrate good agreement with those obtained using the T-15MD soft X-ray diagnostic.
