First Observation of Fishbone-Driven Zonal Flows with Fine Reversed Structure in Tokamak Plasmas
Liutian Gao, Yuehao Ma, Huishan Cai +12
We present the first direct experimental observation of fishbone-driven zonal flows in the core of the EAST tokamak. In contrast to the global pattern predicted by previous models…

A programmable stellarator-tokamak hybrid for million-scale magnetic-configuration discovery
Guodong Yu, Xianyi Nie, Gwanggeun Seo +10
Tokamaks and stellarators are the leading magnetic-confinement concepts for fusion, but they rely on complementary design principles. Tokamaks use simple axisymmetric coils and pla…

Attention-aware convolutional neural networks for identification of magnetic islands in the tearing mode on EAST tokamak
Feifei Long, Yian Zhao, Yunjiao Zhang +16
The tearing mode, a large-scale MHD instability in tokamak, typically disrupts the equilibrium magnetic surfaces, leads to the formation of magnetic islands, and reduces core elect…
