Abstract
  • In this work we present the results obtained applying Singular Value Decomposition (SVD) on a Mirnov coil array in FTU discharges where experiments on MHD stabilization or disruption avoidance via ECRH were performed. In these shots the mode analysis has been consolidated off line by means of FFT and SXR-tomography. Although the Mirnov setting was not necessarily optimised, results show that the algorithm based on SVD is able to detect the mode with a precision equal or better than the FFT, while acting on a smaller time interval. The short execution time required, even in the present preliminary form, suggests that this analysis can be a suitable tool to be implemented in a real time control chain. (literal)
