最近，用低杂波电流驱动(LHCD)在TORE上获得了超过4min的等离子体。这些LHCD等离子体在零环电压下的阻性电流扩散时间超过80倍。在这种独特的条件下，由环形电场驱动的新经典粒子箍缩消失。然而，密度分布保持峰值的时间超过4分钟。首次从实验上证明了在无环向电场的稳态等离子体中存在内向粒子箍缩，远大于碰撞新经典理论的预测值。
Recently, plasmas exceeding 4 min have been obtained with lower hybrid current drive (LHCD) in Tore Supra. These LHCD plasmas extend for over 80 times the resistive current diffusion time with zero loop voltage. Under such unique conditions the neoclassical particle pinch driven by the toroidal electric field vanishes. Nevertheless, the density profile remains peaked for more than 4 min. For the first time, the existence of an inward particle pinch in steady-state plasma without toroidal electric field, much larger than the value predicted by the collisional neoclassical theory, is experimentally demonstrated.
