在JFT-2托卡马克装置上进行了电弧放电的实验研究。电弧伴随着来自限制器的X射线发射。加速电子向限制器提供较大的负偏压电位，并提供足够的鞘层电位以产生弧斑，这是产生电弧的最可能原因。该模型很好地解释了电流上升阶段和等离子体破裂阶段的单极电弧现象。
Experimental study of arcing is made in JFT-2 tokamak. Arcing is accompanied with the X-ray emission from a limiter. It is the most probable cause of arcing that accelerated electrons supply the large negatively biased potential to the limiter and offer the sufficient sheath potential to produce arc spot. This model well explains the monopolar arcing phenomenon in the current rising phase and in the plasma disruption phase.
