Research Abstract

Application of an externally applied rotating magnetic field (RMF) for control of MHD relaxation phenomena driven by a coaxial helicity injection has been proposed in the HIST spherical torus device. As the results, it was clarified that the plasma responses to the RMF depend on not only the driving frequency of the RMF but also the toroidal plasma rotation. In addition, a digital feedback control system has been developed for control of MHD instabilities in the ST devices.
