为了研究静态和旋转共振磁微扰(RMP)与托卡马克等离子体之间的相互作用,在J-TEXT托卡马克装置上设计了两套线圈,即静态RMP(SRMP)和动态RMP(DRMP)。SRMP由TEXT-U重构,主要产生静态的m/n= 1/1,2/1和3/1共振微扰场,其中m和n分别为极向和环向模数。新设计的DRMP安装在真空容器内,可产生纯净的2/1 RMP。DRMP也被设计成在AC模式下工作,并且可以产生旋转的2/1 RMP,其将用于研究撕裂模式控制。当工作频率大于500 Hz时,由于真空室壁中涡流的影响,2/1分量的幅值将衰减到直流值的1/3.6左右。然而,DRMP仍然可以提供足够大的旋转2/1微扰的撕裂模相关的研究。
To investigate the interactions between both the static and rotating resonant magnetic perturbations (RMP) and the tokamak plasma, two sets of coils, namely static RMP (SRMP) and dynamic RMP (DRMP), are constructed on the J-TEXT tokamak. SRMP is reconstructed from TEXT-U and mainly produces staticm/n= 1/1, 2/1 and 3/1 resonant perturbation field, where m and n are the poloidal and toroidal mode numbers, respectively. DRMP, newly designed and installed inside the vacuum vessel, can generate pure 2/1 RMP. DRMP is also designed to operate in the AC mode and can produce rotating 2/1 RMP which will be used to study the tearing mode control. Due to the effect of the eddy current in the vacuum vessel wall, the amplitudes of the 2/1 component will be attenuated to about 1/3.6 of the DC value when the operation frequency is larger than 500 Hz. However, DRMP can still provide sufficient large rotating 2/1 perturbation for tearing mode related studies.
