Temporal and spatial modulation of the edge localized mode (ELM) structure has been observed during the inter-ELM-crash period by toroidally-separated two electron cyclotron emission imaging systems. The observed modulation is interpreted as a beat wave of two modes with adjacent toroidal mode number. An additional assumption is that each mode has to have a different poloidal rotation speed. In nonlinear simulation, the low-n mode can be driven by locking between the dominant modes. The modulation is reconstructed using beat waves not the locking of modes.

周辺局在モード(ELM)構造の時間的・空間的変調が、ELM崩壊間期において、トロイダル方向に分離された2つの電子サイクロトロン放射イメージングシステムによって観測された。観測された変調は、隣接するトロイダルモード数を有する2つのモードのうなり波として解釈される。追加の仮定として、各モードが異なるポロイダル回転速度を有する必要がある。非線形シミュレーションでは、低次のモードが支配的なモード間のロッキングによって駆動され得る。変調は、モードのロッキングではなく、うなり波を用いて再構成される。
