Characterization of Pedestal Burst Instabilities during I-mode to H-mode Transition in the EAST Tokamak
X. M. Zhong, X. L. Zou, A. D. Liu +23
Quasi-periodic Pedestal Burst Instabilities (PBIs), featuring alternative turbulence suppression and bursts, have been clearly identified by various edge diagnostics during I-mode…
The intermittent excitation of geodesic acoustic mode by nonlinear Instanton of electron drift wave envelope in L-mode discharge near tokamak edge
Z. Y. Liu, Y. Z. Zhang, S. M. Mahajan +3
There are two distinct phases in the evolution of drift wave envelope in the presence of zonal flow. A long-lived standing wave phase, which we call the Caviton, and a short-lived…
The theoretical study on intermittency and propagation of geodesic acoustic mode in L- mode discharge near tokamak edge
Zhaoyang Liu, Yangzhong Zhang, Swadesh Mitter Mahajan +8
Through a systematically developed theory, we demonstrate that the motion of instanton identified in [Y. Z. Zhang, Z. Y. Liu, T. Xie, S. M. Mahajan, and J. Liu, Physics of Plasmas…
Intrinsic current drive by electromagnetic electron drift wave turbulence in tokamak pedestal region
Wen He, Lu Wang, Ge Zhuang
The local intrinsic parallel current density driven by electron drift wave (DW) turbulence including electromagnetic (EM) effects is analytically studied. The scalings of the ratio…

I-mode investigation on the Experimental Advanced Superconducting Tokamak
X. Feng, A. D. Liu, C. Zhou +35
By analyzing large quantities of discharges in the unfavorable ion drift direction, the I-mode operation has been confirmed in EAST tokamak. During the L-…
Impurity effects on residual zonal flow in deuterium (D)-tritium (T) plasmas
Weixin Guo, Lu Wang, Ge Zhuang
Significant effects of impurities on residual zonal flow (ZF) in deuterium (D)-tritium (T) plasmas are found. When the gyroradius of impurities is larger (smaller) than that of mai…
Isotopic dependence of impurity transport driven by ion temperature gradient turbulence
Weixin Guo, Lu Wang, Ge Zhuang
Hydrogenic ion mass effects, namely the isotopic effects on impurity transport driven by ion temperature gradient (ITG) turbulence are investigated using gyrokinetic theory. For no…
Investigation of toroidal acceleration and potential acceleration forces in EAST and J-TEXT plasmas
Fudi Wang, Bo Lyu, Xiayun Pan +18
In order to produce intrinsic rotation, bulk plasmas must be collectively accelerated by the net force exerted on them, which results from both driving and damping forces. So, to s…
