[KP01.71] Dynamical stabilization of the internal tilt mode in field-reversed configuration plasmas by rotating magnetic fields: a physical picture

Samuel A. Cohen (Plasma Physics Laboratory, Princeton University)

It is suggested that rotating magnetic fields (RFM) can provide dynamic stabilization of high-s reversed-field-configuration (FRC) plasmas against the internal tilt mode. The approximate stability criterion is (w B_w L)/B_a > V_A, where w is the angular frequency of the RMF, B_w is its amplitude,B_a is the amplitude of the static axial field, L is the length of the FRC, and V_A is the Alfven speed. This is compared with constraints set by current-drive and magnetic field penetration and circulating power power requirements.
