提出了一种估算塔式升级托卡马克先进偏滤器结构撞击点位置的局部展开方法。本文讨论了该技术在DIII-D托卡马克装置上的应用，并对该技术在长腿偏滤器等离子体结构上的性能进行了评估。本文对DIII-D托卡马克装置的等离子体边界重建和偏滤器诊断与局部展开法估算的外撞击点空间位置进行了比较。对于长腿偏滤器等离子体放电外撞击点的空间位置的估计，与平衡重建和诊断数据取得了很好的一致。
A local expansion method has been proposed for estimating the strike point position for the advanced divertor configuration on the MAST Upgrade tokamak. The paper discusses the application and assesses the performance of the technique on a long-legged divertor plasma configuration on an operating device - the DIII-D tokamak. A comparison of the spatial location of the outer strike point estimated with the local expansion method against the plasma boundary reconstruction and divertor diagnostics on the DIII-D tokamak is reported. A good agreement with the equilibrium reconstruction and diagnostic data is achieved with respect to estimation of the spatial location of the outer strike point for the long-legged divertor plasma discharge.
