“…In the context of RFP device design, thorough investigations involving eddy current and stress analyses on toroidal bellows have been conducted using the CAE system [3]. Detailed dynamic analyses of eddy currents and forces within the vacuum vessel have been undertaken during major disruptions, which could potentially inflict severe damage to the TFTR device [4]. The finite element method has been applied to compute eddy currents on magnets during disruptions in the Tore Supra Tokamak [5], and the transient electromagnetic processes in conducting structures have been analyzed through the TYPHOON code on the GLOBUS-M tokamak [6].…”

Since the establishment of the eddy current diagnostic system within the Keda Torus eXperiment (KTX) device, it has unveiled many applications. Recent developments have introduced innovative data analysis techniques alongside compelling experimental results, underscoring the necessity for a comprehensive summary of the system's data analysis approaches and broad applications. Notable features of the system encompass exceptional precision, the ability to encompass shell currents on the entirety of the closed boundary, vector detection of shell currents, and measurement of diverse physical quantities. In terms of data analysis methodologies, meticulous scrutiny of the null field region is conducted, and we reveal a distinctive characteristic within the complex shell current signals, namely the asymmetry of the amplitudes of ±n Fourier coefficients. Moreover, the Hodge decomposition emerges as a pivotal technique, allowing for the distinctive separation of shell currents into three orthogonal components based on their distinct spatial topological properties. With regard to practical applications, an in-depth examination of the vector potential and magnetic helicity flux densities are presented in detail, further highlighting the far-reaching utility of the system's capabilities.
