摘要:

通过线圈形状的直接优化,得到了一个具有四个简单线圈的小型仿星器。新仿星器由两个互锁线圈和两个垂直场线圈组成,类似于哥伦比亚非中性环(CNT)[Pedersen et al. Phys. Rev. Lett. 88,205002(2002)]。优化配置具有全局磁阱和与Wendelstein 7-X(W7-X)相当的低螺旋波纹水平[Wolf等人Nucl. Fusion 57,102020(2017)]。这两个互锁的线圈具有光滑的三维形状,比W7-X等先进仿星器简单得多。这一结果开辟了未来简化线圈仿星器反应堆的可能性。

英文摘要:

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.
