ELM-like activity has been recently observed in TJ-II, in plasmas withstored energy above 1 kJ. The plasma is observed to develop bursts ofmagnetic activity (seen in Mirnov coil signals) which are followed bya large and distinct spike in the Hα signal. An increase inelectrostatic and magnetic fluctuations at the plasma edge and a coldpulse towards the plasma centre are also characteristics of theseevents. In addition, the electron temperature profile locally flattensat the plasma radius where the temperature is in the range 100-200 eV. This flattening can be explained in terms of enhanced electronheat conductivity. Between ELM-like events the electromagneticturbulence at the edge decreases and the Te profiles recover theirformer shapes. This activity is probably triggered by a resonant m = 2, n = 3 mode.

ELM様活動が最近TJ-IIにおいて、蓄積エネルギーが1 kJを超えるプラズマで観測されている。プラズマは、磁気活動のバースト(ミルノフコイル信号に見られる)を発生し、その後にHα信号における大きく明確なスパイクが続くことが観測される。プラズマ端での静電的および磁気的揺動の増加と、プラズマ中心に向かう冷パルスも、これらの事象の特徴である。さらに、電子温度分布は、温度が100-200 eVの範囲にあるプラズマ半径において局所的に平坦化する。この平坦化は、電子熱伝導率の増大によって説明できる。ELM様事象の間には、端での電磁乱流は減少し、Te分布は以前の形状を回復する。この活動はおそらく、共鳴的なm = 2, n = 3モードによって引き起こされる。
