The simulation of ELM control by the advanced divertor configuration in EAST by Y.L. Li, T.Y. Xia, Z.P. Luo, Q.Z. Yu, S.F. Mao, B. Gui, X.X. He, H.M. Qi, P.C. Xie, M.Y. Ye, the EAST team

“…Edge localized modes (ELMs) are effectively suppressed in the ‘quasi-snowflake’ (QSF) divertor discharges, which has been observed in the Experimental Advanced Superconducting Tokamak (EAST). To obtain the physical mechanism of ELM suppression, the numerical simulations are carried out using the BOUT++ turbulence model. …”

Tungsten impurity reduction by ICRH in a high power injection and high performance H-mode discharge on EAST by Zhen Zhou, Shengyu Shi, Ling Zhang, Tao Zhang, Xiaohe Wu, Yunxin Cheng, Wenmin Zhang, Chaowei Mai, Shengyu Fu, Yifei Jin, Xiang Jian, Kaixuan Ye, Lin Yu, Ziqiang Zhou, Jiuyang Ma, Shuqi Yang, Kangning Geng, Gongshun Li, Jia Huang, Fei Wen, Yunfeng Liang, Xiang Gao

“…The decrease in tungsten (W) content with the higher ion cyclotron resonance heating (ICRH) power is observed and explained for the first time in a high power injection ( P _inj > 10 MW), high performance ( β _N ∼ 2, β _P ∼ 2.8, n _e / n _GW ∼ 80%, f _BS ∼ 60%) H-mode discharge on experimental advanced superconducting tokamak. Unlike the previous phenomenon of electron cyclotron resonance heating core W control (Shi et al 2022 Nucl. …”
