Predictive modeling with empirical s.aling for Ohmical heat conductivity s.ows.that in ECRH plas.as.the calculated ion temperature could b. overes.imated, s. an increas. of anomalous.ion heat trans.ort is.required. to s.udy this.effect two s.ans.are pres.nted: over the EC res.nance pos.tion and over the ECRH power. the EC res.nance pos.tion varies.from the high-field s.de to the low-field s.de b. variation of the toroidal magnetic field. the s.an over the heating power is.pres.nted with on-axis.and mixed ECRH regimes.
