Title: Electron inertial effects on rotating magnetic field current drive
Author: Ferrari, HE

Abstract: The effect of finite electron mass on the formation and sustainment of a field reversed configuration (FRC) by rotating magnetic fields (RMF) is studied. The importance of inertial effects is measured by the ratio between the RMF frequency (omega) and the electron-ion collision frequency (nu). In the limit where this ratio is very small (omega/nu -> 0), previous results corresponding to massless electrons are recovered. When omega/nu increases there are significant changes in the value of the minimum external rotating field needed to sustain the FRC and the time required to reach a steady state. Since nu decreases with increasing temperature and decreasing density, these effects are expected to become more important as fusion relevant temperatures are approached.
