Integrated modeling for ion cyclotron resonant heating in toroidal systems
The deployment of high power radio frequency waves in the ion cyclotron range constitutes an important operational facility in many plasma devices, including ITER. Not only for pure heating of the plasma, i.e. Ion Cyclotron Resonant Heating (ICRH), but also for the generation of non-inductive current through Ion Cyclotron Current Drive (ICCD). We concentrate on minority species heating scenario...
متن کاملIon Cyclotron Damping in the Solar Corona and Solar Wind
The solar corona is the hot, ionized outer atmosphere of the Sun. Coronal plasma expands into interplanetary space as a supersonic bulk outflow known as the solar wind. This tenuous and unbounded medium is a unique laboratory for the study of kinetic theory in a nearly collisionless plasma, as well as magnetohydrodynamic waves, shocks, and jets. Particle velocity distributions in the solar wind...
متن کاملOn ion-cyclotron-resonance heating of the corona and solar wind
This paper concisely summarizes and critically reviews recent work by the authors on models of the heating of the solar corona by resonance of ions with high-frequency waves (up to the proton cyclotron frequency). The quasilinear theory of pitch angle diffusion is presented in connection with relevant solar wind proton observations. Hybrid fluid-kinetic model equations, which include wave-parti...
متن کاملSolar Wind Electric Fields in the Ion Cyclotron Frequency Range
In earlier papers (Kellogg and Lin 1997, Kellogg 2000, Kellogg et al 2001) which attempted to understand what effects were responsible for the violation of the conservation of magnetic moment in the solar wind it was pointed out that electric fields in the range which would resonate with the ion cyclotron frequency have not been adequately investigated. In most spinning spacecraft, fields in th...
متن کاملIn Ion-cyclotron Resonance Heating
We determine the conditions under which the damping of the fast Alfven wave, used in the heating of tokamak plasmas, can be described by the geometrical optics approximations. Also, for these conditions, we derive an analytical formula which explicitly determines the amount of energy which is damped onto the plasma particles by the fast wave. The conditions for the validity of the geometrical o...
