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 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...
متن کاملModeling of ion-cyclotron resonant heating in Wendelstein 7-X equilibrium
W7X stellarator 3D equilibrium has been computed with the equilibrium code ANIMEC (Anisotropic Neumann Inverse Moments Equilibrium Code). This equilibrium was used to model ICRH minority heating in 4 He(H) plasma with the 3D full-wave code LEMan (Low frequency ElectroMagnetic wave propagation). The coupled power spatial distribution is shown for different resonance positions within the range of...
متن کاملIon Cyclotron Resonance Heating in The
Ion heating at the fundamental of the cyclotron resonance (1 M H z s 3 MHz) in a toroidal octupole magnetic field is found to be in good agreement with single particle, cold plasma theory at power levels PabrS 100 kW (E 5 100 Vlm) and ion temperatures kT, S 600 eV. Good penetration of the electric field is observed in the densest available plasmas (n7 x lo'* cmA3) with no evidence of parametric...
متن کاملElectron Cyclotron Heating in the Constance 2 Mirror Experiment* Electron Cyclotron Heating in the Constance 2 Mirror Experiment
Electron cyclotron heating of a highly-ionized plasma in mirror geomctry is investigated. Of primary interest is the experimental diagnosis of the elcctron energy distribution and the comparison of the results of this diagnosis with a two dimensional, time-dependent Fokkcr-Planck simulation. 'Tliese two goals are accomplished in four steps. (1) First, the power balance of the heated and unheate...
