English(EN) Physics Attention Transformer Surrogate for Rapid Vertical Instability Growth Rate Prediction: Alcator C-Mod to SPARC

物理注意力 Transformer 加速聚变不稳定性预测

研究人员开发了一个物理注意力 Transformer (PAT) 模型,用于快速预测像 Alcator C-Mod 和 SPARC 这样的聚变反应堆中垂直不稳定性增长率。这种基于 Transformer 的方法在预测标量增长率和扰动环形电流密度空间分布方面,显著优于 FNO2D 和 DeepONet 等其他机器学习模型。PAT 模型在保留数据上实现了低平均绝对误差,并展示了在未来聚变装置中实时控制应用的潜力。 AI

影响 该模型可以实现对聚变反应堆中等离子体不稳定性更快、实时的控制,从而加速聚变能源的研究和开发。
