Mesoscopic transport in KSTAR plasmas: avalanches and the $E \times B$ staircase

The self-organization is one of the most interesting phenomena in the non-equilibrium complex system, generating ordered structures of different sizes and durations. In tokamak plasmas, various self-organized phenomena have been reported, and two of

Report

Experimental evidence of the non-diffusive avalanche-like electron heat transport events and their dynamical interaction with the shear flow structure

We present experimental observations suggesting that the non-diffusive avalanche-like events are a prevalent and universal process of the electron turbulent heat transport in tokamak core plasmas. They are observed in the low confinement mode and the

SOL width and intermittent fluctuations in KSTAR

Autor: Garcia, O. E., Kube, R., Theodorsen, A., Bak, J. -G., Hong, S. -H., Kim, H. -S., Team, the KSTAR Project, Pitts, R. A.

Radial profiles of the ion saturation current and its fluctuation statistics are presented from probe measurements in L-mode, neutral beam heated plasmas at the outboard mid-plane region of KSTAR. The familiar two-layer structure, seen elsewhere in t

First evidence of Alfven wave activity in KSTAR plasmas

Autor: Hole, M. J., Ryu, C. M., Woo, M. H., Bak, J. G., Sharapov, S E., Fitzgerald, M., team, the KSTAR

We report on first evidence of wave activity during neutral beam heating in KSTAR plasmas: 40 kHz magnetic fluctuations with a toroidal mode number of n=1. Our analysis suggests this a beta-induced Alfven eigenmode resonant with the q=1 surface. A ki

Dynamics and statistics of a self-organized temperature corrugation in tokamak plasmas

Autor: Choi, Minjun J., Kwon, Jae-Min, Qi, Lei, Diamond, P. H., Hahm, T. S., Jhang, Hogun, Kim, Juhyung, Leconte, M., Kim, Hyun-Seok, Park, Byoung-Ho, Chung, Jinil, Lee, Jaehyun, Kim, Minho, Yun, Gunsu S., Ko, Won-Ha, Lee, K. D., Juhn, J. W., team, the KSTAR

Turbulent transport near the marginal stability of tokamak plasmas is dominated by non-diffusive avalanche transport events in gyrokinetic simulations. The avalanche transport events are found to interact with self-organized shear flow layers, or the
