摘要：Linear gyrokinetic simulations using the GTC code have been carried out to study microturbulence in dominant electron heating plasma on EAST tokamak experiments. Results indicate that TEM is the main microturbulence during dominant electron heating. TEM linear growth rate γ is increased with normalized temperature gradient R/LTE. Moreover, the transition from TEM to ITG mode is observed during NBI combining with other dominant electron heating method. NBI power transfer to ions is larger and broader along minor radius than that to electrons after TEM to ITG transition. Significant variation of R/LTi may be the main reason of TEM-ITG mode transition when the other plasma parameters are constant. ? 45th EPS Conference on Plasma Physics, EPS 2018. All rights reserved.
