9个星体构型，3个准轴对称的，3个准螺旋对称的和3个非准对称的，被标度到Aries-CS尺寸，并分析了含能粒子的含量。在高能粒子约束方面表现最好的组态在新古典主义Γc度规上也表现得最好，该度规试图将第二绝热不变量的轮廓与通量表面对齐。同时在Γc和准对称性上表现良好的准对称组态具有最好的整体约束，碰撞损耗低于3%，接近铁素体镶嵌的ITER的性能。
Nine stellarator configurations, three quasiaxisymmetric, three quasihelically symmetric and three non-quasisymmetric are scaled to ARIES-CS size and analyzed for energetic particle content. The best performing configurations with regard to energetic particle confinement also perform the best on the neoclassical Γc metric, which attempts to align contours of the second adiabatic invariant with flux surfaces. Quasisymmetric configurations that simultaneously perform well on Γc and quasisymmetry have the best overall confinement, with collisional losses under 3%, approaching the performance of ITER with ferritic inserts.
