Behavior of geodesic acoustic mode and limit-cycle oscillation approaching L-H transition in JFT-2M tokamak

In this paper, a phenomenology of competing behavior between the geodesic acoustic mode (GAM) and the limit-cycle oscillation (LCO) is presented. Before the LCO occurs, the GAM can grow to the observable amplitude via the turbulent Reynolds stress force. Approaching the L-H transition, the LCO is excited and the GAM decays. In the LCO phase, the GAM driving force is possibly suppressed by the nonlocal turbulence amplitude modulation by the LCO.

本論文では、測地線音響モード(GAM)とリミットサイクル振動(LCO)の間の競合挙動の現象論を提示する。LCOが発生する前に、GAMは乱流レイノルズ応力を通じて観測可能な振幅まで成長し得る。L-H遷移に近づくと、LCOが励起され、GAMは減衰する。LCO位相では、GAMの駆動は、LCOによる非局所的な振幅変調によっておそらく抑制される。
