Multiplot of the 2D runs at saturation ordered by increasing suppression of thermal diffusivity (from left to right). From top to bottom: Magnitude of the velocity field, density fluctuation, Boussinesq plasma beta, Boussinesq parallel temperature length, point-wise thermal diffusion suppression fraction. The color bar is in common for each row. A higher suppression parameter α leads to weaker MTI turbulence, weaker magnetic fields (higher $\stackrel{\sim }{\beta }$), less isothermal fieldlines (higher σ), and lower average thermal conductivity χ.
