Giant edge localized modes (ELMs) play an important role in the transport of plasma at the edge of tokamaks with a divertor. The loss of plasma, by mechanisms that are not well understood, causes very high power loading on parts of the wall structure. The flows of particles and energy have been determined on a rapid time-scale for the first time in JET. The soft X ray measurements have a complex structure and show a rapid onset of the instability. They prove that some plasma is lost outside the divertor and that recycling occurs to well within the separatrix. The implications of the results for the ELM instability mechanism and the design of tokamaks are discussed.

周辺局在モード(ELM)は、ダイバータを有するトカマクの周辺プラズマ輸送において重要な役割を果たす。十分に理解されていない機構によるプラズマ損失は、壁構造の一部に非常に高い電力負荷を引き起こす。粒子およびエネルギーの流束は、JETにおいて初めて高速時間スケールで測定された。軟X線測定は複雑な構造を示し、不安定性の急速な発生を明らかにした。それらは、プラズマの一部がダイバータの外側に失われ、リサイクリングがセパラトリックスの内側深くまで発生することを証明している。ELM不安定性機構およびトカマク設計に対するこれらの結果の意義について考察する。
