Mesoscopic transport in KSTAR plasmas: avalanches and the staircase
Minjun J. Choi, Jae-Min Kwon, Lei Qi +18
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 pla…
Stochastic fluctuation and transport of tokamak edge plasmas with the resonant magnetic perturbation field
Minjun J. Choi, Jae-Min Kwon, Juhyung Kim +17
We present that a statistical method known as the Complexity-Entropy analysis is useful to characterize a state of plasma turbulence and flux in the resonant magnetic perturbation…
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…
Observation of non-local effects in ion transport channel in J-TEXT plasmas
Yuejiang Shi
In cold pulse experiments in J-TEXT, the ion transport shows similar non-local response as the electron transport channel. Very fast ion temperatures decreases are observed in the…
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…
Multiscale interaction between a large scale magnetic island and small scale turbulence
M. J. Choi, J. Kim, J. -M. Kwon +13
Multiscale interaction between the magnetic island and turbulence has been demonstrated through simultaneous two-dimensional measurements of turbulence and temperature and flow pro…
