The inward particle flux associated with the global long-lived mode (LLM) during the L–I–H transition on HL-2A tokamak has been measured. The inward particle flux arises from the phase change between density and radial velocity fluctuations, where density and velocity fluctuations are strongly correlated with magnetic fluctuations of LLM. Moreover, the radial velocity and its gradient rather than poloidal flow shear play an important role in particle transport associated with the large-scale mode. The strong nonlinear coupling between LLM and ambient turbulence has been confirmed, and this may contribute to most of the inward particle flux in the LLM during the I-phase state.

HL-2AトカマクにおけるL-I-H遷移中の大域的長寿命モード(LLM)に伴う内向き粒子束が測定された。内向き粒子束は、密度と半径方向速度の揺動間の位相変化に起因し、ここで密度と速度の揺動はLLMの磁気揺動と強く相関している。さらに、大規模モードに関連する粒子輸送においては、ポロイダル流のシアよりも半径方向速度とその勾配が重要な役割を果たす。LLMと周囲の乱流との間の強い非線形結合が確認され、これがI相状態におけるLLM中の内向き粒子束の大部分に寄与している可能性がある。
