The comparison between modeling of edge localized modes with a current relaxation model and experiment on EAST

J Q Cai, Y Liang, J Pearson, T Zhang, Q Zang, M Q Wu, J Huang, EAST Team2017年Plasma Physics and Controlled FusionIF 2.2出版社

The distinctions of edge localized mode (ELM) frequency distributions between moderate and high edge current density cases were observed on the experiment advanced superconducting tokamak. In this paper, a current relaxation model is applied to explain this new observation. It has been demonstrated that the ELM frequency is very sensitive to the edge current density and the edge safety factor by the model predictions. The results also show that, in the large edge current density case, the ELM frequency is subject to a single-peak distribution; while in the moderate edge current density case, the ELM frequency is subject to a roughly multi-peak distribution.

周辺電流密度が中程度の場合と高い場合における周辺局在モード(ELM)周波数分布の差異が、実験先進超伝導トカマクにおいて観測された。本論文では、この新たな観測結果を説明するために電流緩和モデルを適用する。モデル予測により、ELM周波数は周辺電流密度と周辺安全係数に非常に敏感であることが実証された。また、結果は、周辺電流密度が大きい場合にはELM周波数が単峰分布を示す一方、周辺電流密度が中程度の場合にはELM周波数がおおよそ多峰分布を示すことを明らかにした。
