AI总结:

本文采用单阶段直接线圈优化,将等离子体约束、稳定性与工程约束统一求解,获得少线圈及一至三线圈准对称等多种简化灵活的仿星器新构型。

摘要:

单阶段优化,也称为组合等离子体–线圈算法或直接线圈优化,近来作为一种可能加快仿星器装置设计的方法而出现,它在单个步骤中同时纳入约束、稳定性和工程约束。在本工作中,我们展示此类框架如何使我们以流线化方式找到新设计,产生范围广泛的新构型。文中给出了若干示例:具有少量线圈的仿星器,以及每个半场周期仅用一至三个线圈的准对称仿星器,并配有外部微调线圈、螺旋线圈,以及单组线圈同时产生准轴对称和准螺旋平衡的构型。

英文摘要:

Single-stage optimization, also known as combined plasma-coil algorithms or direct coil optimization, has recently emerged as a possible method to expedite the design of stellarator devices by including, in a single step, confinement, stability, and engineering constraints. In this work, we show how such frameworks allow us to find new designs in a streamlined manner, yielding a broad range of new configurations. Examples are shown for stellarators with a small number of coils and quasisymmetric stellarators with only one to three coils per half field period, with external trim coils, helical coils, and a single set of coils generating both a quasi-axisymmetric and a quasi-helical equilibrium.
