A helical coil winding law has been found for a stellarator with many of the desirable properties of the Helias. High performance computer codes make it possible to optimize the configuration over a parameter space of large dimension. For reactor applications an ample gap is provided between the coils and the plasma. Line tracing shows that the magnetic surfaces are robust. Non-linear stability at high beta is verified by equilibrium calculations in three dimensions. A neoclassical theory of transport taking quasi-neutrality into account predicts that energy confinement times sufficient for ignition can be achieved economically. For power plant studies a more attractive modular version of this concept called the MHH stellarator is under investigation
恒星状器的一种螺旋线圈绕制规律已被发现，其具有Helias的许多理想特性。高性能计算机代码使得在较大维度的参数空间内优化位形成为可能。对于反应堆应用，线圈与等离子体之间提供了充足的间隙。磁力线追踪表明磁面具有鲁棒性。三维平衡计算验证了高β下的非线性稳定性。考虑准中性的新经典输运理论预测，能够以经济的方式实现足以点火所需的能量约束时间。针对电站研究，正在研究该概念的更具吸引力的模块化版本，称为MHH恒星状器。
