Poloidal current drive by rotating magnetic field

Summary form only given. The non-inductive current drive is a key issue in fusion oriented research. In order to control or sustain the magnetic field configuration of reversed field pinch (RFP) plasmas, the poloidal current drive by rotating magnetic fields (RMF) is one of the promising means. This method also can be used to generate and maintain the field reversed configuration (FRC) steadily. Simulation results show that for high temperature plasmas, taking account of the electron inertia, the rise time of driven current is much shorter than that in the case when the electron inertia is neglected. Thus, it is shown that in high temperature plasmas the electron inertia plays a crucial role in the current drive by the RMF.
