Experimental observation of local outward particle flux induced by electron cyclotron resonance heating

摘要

The density perturbation induced by electron cyclotron resonance heating was examined on the JFT-2M tokamak using two different heating methods, a pulse injection and a modulated injection. The measured temporal behaviours of the density perturbations were compared with numerical simulations, in which the ECRH induced flux was modelled as local outward flux. It was found that this model can explain the measured density perturbation satisfactorily.
