摘要
本文展示了 MAST 的最新结果，重点关注验证模型以便外推到未来的装置。启动实验期间的测量表明，体离子温度的升高与重连磁场的平方成正比。在电流上升阶段，模型无法正确预测电流扩散。已进行了观察边缘和核心湍流的实验。在边缘处，详细的研究揭示了丝状结构特征如何决定近场和远场 SOL 密度分布。在核心处，测量了本征旋转和电子尺度湍流。快离子梯度通过鱼骨模重新分布快离子的作用，促使 MAST Upgrade 上的中性束注入器进行了重新设计。在 H 模式中，台架顶部的湍流被证明与电子温度梯度模一致。在 ELM 期间似乎发生了重连过程，释放的丝状结构数量决定了偏滤器上的功率分布。只要边缘剥离响应最大化且核心扭曲响应最小化，共振磁扰动就可以缓解 ELM。已证明具有环向模数 n>1 的本征误差场缓解对等离子体性能具有重要意义。
