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...
متن کاملElectron Plasmas Cooled by Cyclotron-Cavity Resonance.
We observe that high-Q electromagnetic cavity resonances increase the cyclotron cooling rate of pure electron plasmas held in a Penning-Malmberg trap when the electron cyclotron frequency, controlled by tuning the magnetic field, matches the frequency of standing wave modes in the cavity. For certain modes and trapping configurations, this can increase the cooling rate by factors of 10 or more....
متن کاملIon Cyclotron Resonance Heating in a Toroidal Octupole
A 1 MW� 2 msec pulse of rf power at the ion cyclotron frequency (2.6 MHz) has been used to heat the ions from < 1 eV to 350 eV in a toroidal octupole device. The ion temperature is limited by charge exchange loss and agrees quantitatively with theoretical predictions. No parametric decay waves, enhanced diffusion, or other deleterious effects except for a high neutral re flux are observed to a...
متن کاملPfc/ja-83-13 Parametric Phenomena in Electron Cyclotron Resonance Heating of Tokamak Plasmas
A theoretical study of parametric processes near the electron cyclotron resonance region in tokamak plasmas is presented. Parametric dispersion relations, including finite wave length of the driver pump, of principal and harmonic parametric excitations, are given. The problem of primary and secondary decays including their temporal and spatial growth rates is studied. In the nonlinear phase of ...
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...
