Research on the effect of resonant magnetic perturbations on disruption limit in J-TEXT tokamak

The effect of resonant magnetic perturbations (RMPs) on high density limit and low-q limit discharges is studied in J-TEXT tokamak. It is found that a moderate amplitude of applied RMPs increases the density limit and delays the disruption, and the disruption precursor is suppressed with a slight reduction in toroidal plasma rotation. A too large amplitude of RMPs, however, leads to a lower density limit and an earlier disruption. For the optimal RMPs amplitude, the disruption is delayed by about 150 ms. For low-q discharges, the applied static RMP can either lower the limit of the edge safety factor qa from 2.15 to nearly 2.0 or sustain stable plasma discharge with qa  =  2.1, and the disruptive precursor is also suppressed.

J-TEXTトカマクにおいて、高密度限界および低q限界放電に対する共鳴磁気摂動(RMP)の効果が研究される。適度な振幅のRMP印加は密度限界を増加させ、ディスラプションを遅延させることが見出され、ディスラプション前駆体はトロイダルプラズマ回転のわずかな減少を伴って抑制される。しかしながら、大きすぎるRMP振幅は密度限界を低下させ、より早いディスラプションを導く。最適なRMP振幅では、ディスラプションは約150 ms遅延される。低q放電に対しては、印加された静的RMPはエッジ安全係数qaの限界を2.15からほぼ2.0へ下げるか、またはqa = 2.1で安定なプラズマ放電を維持することができ、ディスラプション前駆体も同様に抑制される。
