论文摘要
具有四个简单线圈的优化紧凑型恒星通过线圈形状的直接优化获得。新的易位仪由两个互锁线圈和两个与哥伦比亚非中性圆环（CNT）相似的垂直场线圈[Pedersen等。物理。莱特牧师。 88，205002（2002）]。优化的配置具有全局磁孔，低螺旋纹波水平与Wendelstein 7-X（W7-X）相当[Wolf等。 nucl。 Fusion 57，102020（2017）]。这两个互锁线圈的三维形状比高级恒星（例如W7-X）要简单得多。该结果开辟了使用简化的线圈的未来恒星反应堆的可能性。
An optimized compact stellarator with four simple coils is obtained from direct optimization via coil shape. The new stellarator consists of two interlocking coils and two vertical field coils similar to those of the Columbia Non-neutral Torus (CNT)[Pedersen et al. Phys. Rev. Lett. 88, 205002 (2002)]. The optimized configuration has global magnetic well and a low helical ripple level comparable to that of Wendelstein 7-X (W7-X)[Wolf et al. Nucl. Fusion 57, 102020 (2017)]. The two interlocking coils have a smooth three-dimensional shape much simpler than those of advanced stellarators such as W7-X. This result opens up possibilities of future stellarator reactors with simplified coils.
