Stabilization of Interchange Modes in Mirror Plasma Devices by Radio-Frequency Sideband Coupling

Abstract: We present results from an analysis of the ion cyclotron range of frequencies (ICRF) wave interactions with flute-interchange modes. The analysis is valid for an arbitrary wave vector of the ICRF waves, and shows that these modes can be stabilized by ICRF sideband coupling to them. The modes can be stabilized in a variety of ways, depending on details of the ICRF wave structure. We also find a new rf-driven fluid instability for a range of parallel (to the magnetic field) rf wavelengths.PACS numbers: 52.35.Py,… Show more

“…The weak turbulence theory in which the fluid variables are expanded in powers of rf amplitude, was utilized under the assumption of electrostatic SBWs. 8 The physics underlying the SBC process and its impact on the interchange stability is a little more complicated than that of the EPM mechanism. The nonlinear coupling between the interchange mode and the applied rf wave generates SBWs with wave vectors k Ϯ ϭk 0 Ϯk and angular frequencies Ϯ ϭ 0 Ϯ.…”
