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…
Edge Temperature Ring Oscillation Modulated by Turbulence Transition for Sustaining Stationary Improved Energy Confinement Plasmas
A. D. Liu, X. L. Zou, M. K. Han +33
A reproducible stationary improved confinement mode (I-mode) has been achieved recently in the Experimental Advanced Superconducting Tokamak, featuring good confinement without par…
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-…
