Effects of plasma turbulence on the nonlinear evolution of magnetic island in tokamak
Minjun J. Choi, Laszlo Bardoczi, Jae-Min Kwon +7
Magnetic islands (MIs), resulting from a magnetic field reconnection, are ubiquitous structures in magnetized plasmas. In tokamak plasmas, recent researches suggested that the inte…

Experimental evidence of the non-diffusive avalanche-like electron heat transport events and their dynamical interaction with the shear flow structure
Minjun J. Choi, Hogun Jhang, J. -M. Kwon +12
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 tokam…

Distinct stages of radio frequency emission at the onset of pedestal collapse in KSTAR H-mode plasmas
Minho Kim, Shekar G. Thatipamula, Jieun Lee +4
Using a high-speed and broadband radio frequency (RF) (0.1-1 GHz) spectrum analyzer developed on the KSTAR tokamak, it is found that several distinct stages of RF emission appear a…
