摘要为白羊座-CS研制出了新颖的星光配置。这些配置经过优化，可在高贝塔条件下提供良好的等离子体约束和通量表面完整性。模块线圈是为它们设计的，其中繁殖毯子和辐射屏蔽所需的空间是专门针对的，这样产生GW电力的反应堆只需要中等大半径(<；10米)。这些构型在磁场拓扑中是准轴对称的，并且具有少量的场周期(≤3)和低长宽比(≤6)。为详细的系统和发电厂研究选择的基线设计有三个现场周期，宽高比4.5m，主半径7.5m，在β~6.5%下运行，产生1GW的电力。等离子体的整形占旋转变换的≥的75%。有效螺旋波纹很小(到处都是0.6%)，计算出在高密度区工作时，α粒子的能量损失为≤5%。这种构型中一个有趣的特征是，我们没有最小化磁谱中的所有残基，而是优先保留了少量的非轴对称镜像场。这种反射镜及其相关螺旋场的存在改变了波纹分布，导致了尽管托卡马克类场结构中的连接长度很长，但α粒子的波纹陷阱损失减少了。此外，我们还讨论了另外两类可能有吸引力的位形，都是准轴对称的：一种只有两个场周期，很低的长宽比(~2.5)，不太复杂的线圈；另一种是等离子体整形，旨在产生低剪切旋转变换，以确保在高β下运行时磁通面的稳健性和完整性。
Abstract Novel stellarator configurations have been developed for ARIES-CS. These configurations are optimized to provide good plasma confinement and flux surface integrity at high beta. Modular coils have been designed for them in which the space needed for the breeding blanket and radiation shielding was specifically targeted such that reactors generating GW electrical powers would require only moderate major radii (<10 m). These configurations are quasi-axially symmetric in the magnetic field topology and have small numbers of field periods (≤3) and low aspect ratios (≤6). The baseline design chosen for detailed systems and power plant studies has three field periods, aspect ratio 4.5, and major radius 7.5 m operating at β ~ 6.5% to yield 1 GW of electric power. The shaping of the plasma accounts for ≥75% of the rotational transform. The effective helical ripples are very small (<0.6% everywhere), and the energy loss of alpha particles is calculated to be ≤5% when operating in high-density regimes. An interesting feature in this configuration is that instead of minimizing all residues in the magnetic spectrum, we preferentially retained a small amount of the nonaxisymmetric mirror field. The presence of this mirror and its associated helical field alters the ripple distribution, resulting in the reduced ripple-trapped loss of alpha particles despite the long connection length in a tokamak-like field structure. Additionally, we discuss two other potentially attractive classes of configurations, both quasi-axisymmetric: one with only two field periods, very low aspect ratios (~2.5), and less complex coils, and the other with the plasma shaping designed to produce low-shear rotational transform so as to ensure the robustness and integrity of flux surfaces when operating at high β.
