  Wave-particle interaction in toroidal plasmas is an essential transport
mechanism in drift wave instability-driven microturbulence. In tokamkas,
different wave-particle resonance conditions have been found important for the
energy and particle transport of multiple species in various drift wave
turbulences. To confirm the transport mechanism for electrons and ions in
tokamak drift-wave instabilities, the effect of wave-particle resonance on
turbulent transport is studied using global gyrokinetic particle simulations of
the plasma core ion temperature gradient (ITG) and collisionless trapped
electron mode (CTEM) turbulence. Simulation results show that in CTEM and ITG
turbulence, electron transport is primarily regulated by wave-particle linear
resonance, and the ion transport is regulated by nonlinear wave-particle
decorrelation.
