摘要：
The plasma energy confinement in CTX mesh flux conservers appears to be dominated by relaxation fluctuations which drive current in the resistive plasma edge region. Strong ion heating is expected from these relaxation processes. The paper presents new data, from previously studied decaying discharges, which show impurity oxygen ion Doppler temperatures much above the Thomson scattering electron temperature. In addition, using the standard MHD equilibrium model by Knox et al., and the resistivity model previously described by Fernandez et al., the contribution of relaxation fluctuations to spheromak current drive along the open magnetic field lines at the spheromak edge can be estimated. © 1990 IOP Publishing Ltd.
