从MAST的新结果提出，重点是验证模型，以便外推到未来的设备。在启动实验期间的测量显示了体离子温升如何随重连接场的平方而变化。在电流上升期间，模型不能正确预测电流的扩散。已经进行了观察边缘和核心湍流的实验。在边缘，详细的研究揭示了长丝特性是如何决定近和远刮脱层密度分布的。在核心中测量了固有旋转和电子尺度湍流。快速离子梯度对通过鱼骨模式重新分配快速离子的作用导致了MAST升级项目中中性束注入器的重新设计。在h模式下，基座顶部的湍流被证明是由电子温度梯度模式引起的。在边缘局域模式（elm）期间会发生重接过程，释放的灯丝数量决定了分流器的功率分布。如果边缘剥离响应最大化，核心扭结响应最小化，共振磁扰动可以减轻elm。减缓环面模式数为> 1的本征误差场对等离子体性能非常重要。
New results from MAST are presented that focus on validating models in order to extrapolate to future devices. Measurements during start-up experiments have shown how the bulk ion temperature rise scales with the square of the reconnecting field. During the current ramp-up, models are not able to correctly predict the current diffusion. Experiments have been performed looking at edge and core turbulence. At the edge, detailed studies have revealed how filament characteristics are responsible for determining the near and far scrape off layer density profiles. In the core the intrinsic rotation and electron scale turbulence have been measured. The role that the fast ion gradient has on redistributing fast ions through fishbone modes has led to a redesign of the neutral beam injector on MAST Upgrade. In H-mode the turbulence at the pedestal top has been shown to be consistent with being due to electron temperature gradient modes. A reconnection process appears to occur during edge localized modes (ELMs) and the number of filaments released determines the power profile at the divertor. Resonant magnetic perturbations can mitigate ELMs provided the edge peeling response is maximised and the core kink response minimised. The mitigation of intrinsic error fields with toroidal mode number n > 1 has been shown to be important for plasma performance.
