等离子体破裂是影响托卡马克装置实现商业发电的一大难题。等离子体大破裂会导致等离子体在瞬间熄灭，同时会对装置本身以及装置的第一壁材料形成巨大损伤。等离子体破裂时会产生大量高能逃逸电子，从而把一部分等离子体电流转化为逃逸电流。逃逸电流在一定的情况下会局域地沉积到装置的第一壁上，从而影响壁材料的寿命和性能，观察研究等离子体破裂下电流的熄灭特征以及逃逸电流的特征，探寻降低等离子体破裂危害的方法至关重要。

Plasma disruption has a negative influence on the realization of the commercial power generation in TOKAMAK. Disruption will lead the plasma to extinguish, and in the meanwhile, it may damage the first wall of the setups. Plasma disruption can produce a mass of high energy runaway electrons, which make a part of the plasma currents transform to runaway currents. In certain situations runaway current will be deposited to the first wall of the setups, which may affect the lifetime and properties of the materials. In the paper, the characteristics of the quenched current under disruption and the runaway current are demonstrated.
