摘要

在Globus-M型托卡马克的中性束加热h模放电中，锯齿振荡触发边缘局域模式(ELM)的开始。触发的elm在开始前小于0.2 ms有磁振荡前兆，具有典型的岛状旋转频率。本文讨论了部分重联引起的电流密度分布变宽所引起的剥落-气球(P-B)不稳定。

The ELM triggering by sawtooth oscillations

In the H-mode discharges with the neutral beam heating (NBI) in the Globus-M tokamak the sawtooth oscillations are triggering the edge localised modes (ELM) onset. The triggered ELMs have the magnetic oscillation precursor less than 0.2 ms before the onset with the typical island rotation frequency. The paper discussing the peeling-ballooning (P-B) destabilisation caused by the current density profile broadening due to partial reconnection.
