Rapid transitions of the toroidal mode number () have been often detected during the evolution of the edge localized modes (ELMs) in the inter-ELM-crash periods of the KSTAR tokamak plasmas. The mode number transitions accompany changes of the mode frequency () (e.g. changed from 8 to 5 while changed from ~32 to 9 kHz). The observed transition phenomena have been diverse including small and large increase (or decrease) in the mode number and multiple transitions during a single inter-ELM-crash period. Two classes of the mode transitions were identified: non-overlapping transition and overlapping transition. The former case is characterized by the absence of coherent filamentary structure during the transition and the latter case is characterized by co-existence of two coherent filamentary structures with different mode numbers. Each transition process typically lasts a few hundreds to thousands of μs.

KSTARトカマクプラズマのELMクラッシュ間期において、周辺局在モード(ELM)の時間発展中にトロイダルモード数()の急速な遷移がしばしば検出されている。モード数の遷移にはモード周波数()の変化が伴う(例えば、が8から5へ変化する一方で、が約32から9 kHzへ変化した)。観測された遷移現象は多様であり、モード数の小さな増加・減少から大きな増加・減少までを含み、また単一のELMクラッシュ間期における複数回の遷移も含まれる。モード遷移には2つのクラスが同定された:非重複遷移と重複遷移である。前者のケースは遷移中にコヒーレントなフィラメント構造が存在しないことを特徴とし、後者のケースは異なるモード数を持つ2つのコヒーレントなフィラメント構造が共存することを特徴とする。各遷移プロセスは典型的には数百から数千μsの時間スケールで進行する。
