Electron drift effects on magnetic islands in a hot-electron plasma are studied. The slab approximation is used. The electron temperature gradient is neglected. The authors analyze the properties of the electrostatic potential profile function and the density profile function in the presence of the electron drift effects and the problem of regularization of these profile functions near the island separatrix. It is emphasized that the electron drift frequency depends on the island magnetic flux and, as a result of this dependence, the resonant interaction of magnetic islands with the electron drift waves is possible. It is shown that, allowing for the finiteness of the “effective” ion Larmor radius ρ[sub s] (the ion sound radius), the polarization current effect proves to be dependent on the electron drift effects. © 2001 American Institute of Physics.
