Local analysis of mode conversion at S=n(2)(z) resonances in the ion cyclotron range of frequenciesFunded under: FP2-FUSION 10C
For the S=n(2,z) resonances in the ion cyclotron heating of tokamak plasmas, a simple formula is derived which relates the converted fast wave power flux to the local dielectric tensor elements and to the fast wave electric field at the resonance. The validity of this estimate is analysed for finite electron inertia and finite temperature and its usefulness in predicting the conversion at the edge plasma resonances is demonstrated.
