Anomalous ion heat transport is analyzed.in the t-10 tokamak plasma heated.with electron cyclotron resonance heating(ECRH) in second.harmonic extra-ord.nary mod.. Pred.ctive mod.ling with empirical scaling for Ohmical heat cond.ctivity shows that in ECRH plasmas the calculated.ion temperature could.be overestimated. so an increase of anomalous ion heat transport is required. to stud. this effect two scans are presented. over the EC resonance position and.over the ECRH power. the EC resonance position varies from the high-field.sid. to the low-field.sid. by variation of the toroid.l magnetic field. the scan over the heating power is presented.with on-axis and.mixed.ECRH regimes. d.scharges with high anomalous ion heat transport are obtained.in all consid.red.regimes. In these d.scharges the power balance ion heat cond.ctivity exceed. the neoclassical level by up to 10 times. the high ion heat transport regimes are d.stinguished.by three parameters: the ratio te/ti, the normalized.electron d.nsity grad.ent R/■, and.the ion–ion collisionality νii~*. the combination of high te/ti, high νii~*, and.R/■=6-10 results in values of normalized.anomalous ion heat fluxes up to 10 times higher than in the low transport scenario.
