The aim of this article is to describe and model a sawtooth crash in RFX-mod2 and compute the eddy currents induced in the stabilizing shell surrounding the plasma for two alternative gap concepts and the subsequent error field. The sawtooth crash displacement of the plasma column is represented by a vacuum model coupled with a suitable magneto-quasi-static (MQS) volume integral (VI) formulation.

RFX-mod2反向场捏中的误差场计算

本文的目的是描述和建模RFX-mod2中的锯齿形碰撞，并针对两个替代的间隙概念和随后的误差场，计算在围绕等离子体的稳定壳中感应出的涡电流。等离子柱的锯齿形碰撞位移由真空模型与合适的磁准静态（MQS）体积积分（VI）公式耦合表示。
