Numerical simulations have been carried out to study how resonant magnetic perturbation (RMP) affects the loss of energetic passing ions. The loss fractions are compared between RMPs without and with the plasma response included, namely vacuum and response RMPs. The significant role of the RMP spectrum is revealed. More interestingly, inclusion of the plasma response, which to a large extent heals the magnetic topology, does not necessarily lead to a better confinement. In order to better interpret the result, it is crucial to clarify how the RMP spectrum affects drift islands. Due to magnetic drift, the structure of drift islands is essentially different from the magnetic topology. The primary contribution from resonant components and the sideband contribution from non-resonant components are compared in detail for the first time by tailoring the RMP spectrum. It is found that both contributions play an important role in the formation of drift islands under a realistic RMP. In ...

初级和边带共振在共振磁扰动下限制高能传递离子的作用

已经进行了数值模拟以研究共振磁扰动(RMP)如何影响高能传递离子的损失。比较在不包括血浆反应和包括血浆反应的RMP之间的损失分数,即真空和反应RMP。揭示了RMP频谱的重要作用。更有趣的是,包含等离子响应(在很大程度上治愈了磁拓扑)并不一定导致更好的限制。为了更好地解释结果,弄清RMP频谱如何影响漂移岛至关重要。由于磁漂移,漂移岛的结构与磁拓扑本质上不同。通过定制RMP频谱,首次详细比较了谐振分量的主要贡献和非谐振分量的边带贡献。发现在实际的制冷剂管理计划下,这两种贡献在漂移岛的形成中都起着重要作用。在...
