Ion-Cyclotron Resonance Heating of Plasmas and Associated Longitudinal Cooling

In 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...

Ion 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...

Self Consistent Calculations of Ion Cyclotron Resonance Heating in Toroidal Plasmas

A method for self consistent calculations of ion cyclotron resonance heating has been developed. The dielectric tensor is calculated from a particle distribution function calculated with the orbit averaged Monte Carlo code fido. The tensor is then fed into the global wave code lion. The calculated wave field and power partitions are fed back into the fido code. By using two existing codes in an...
