In conventional local turbulence simulations on ion-scale turbulence such as the ion temperature gradient turbulence, electrons have been assumed to respond adiabatically. In particular, passing electrons are considered to be adiabatic because of their fast motion along the magnetic field line. On the contrary, a recent study shows that non-adiabatic, i. e., kinetic responses of passing electrons can be important near the low-order mode rational surface, and they can contribute to heat and particle transport. In the presentation, we will show the impacts of passing electrons on the heat and particle transport through comparisons of local turbulence simulations employing different kinetic electron models.
