Description

Investigation of ion heat conductivity in plasma with ECR-heating and suppressed saw-teeth and modes $(m,n)=(1,1)$ and $(2,1)$ is carried out. Off-axis heating (localization radius is $\rho=r/a \approx0.5$) and combined heating (on-axis ECRH together with off-axis) are considered. It is shown for the ohmic stage that ion heat conductivity is on a neoclassical level in the central zone $\rho \leq 0.5-0.6$ but it is clearly anomalous outside these radii. Off-axis heating does not lead to any notable changes of the heat conductivity profile. In the regime with combined heating additional $\approx0.5$ MW on-axis ECR-power results in ion heat conductivity magnification up to $\approx1.5$ times and $\approx1$ MW on-axis ECR-power causes the increase up to $\approx2$ times.
