论文摘要
我们提出了一种新的方法，用于数字发现具有出色的快速粒子约束和极小的新古典传输的准静脉恒星磁场。该方法在仅一个字段周期的配置中效果特别好。我们检查了这些新发现的准iS动力学构型的性能，包括它们的引导电流，粒子限制和可用的捕获 - 电子驱动湍流的能量，以及当添加有限压力剖面时它们更改的程度。我们最终讨论了优化溶液的磁轴及其各自的初始条件之间的差异，并以未来的准iS动力优化的前景结论。
We present a novel method for numerically finding quasi-isodynamic stellarator magnetic fields with excellent fast-particle confinement and extremely small neoclassical transport. The method works particularly well in configurations with only one field period. We examine the properties of these newfound quasi-isodynamic configurations, including their bootstrap currents, particle confinement, and available energy for trapped-electron driven turbulence, as well as the degree to which they change when a finite pressure profile is added. We finally discuss the differences between the magnetic axes of the optimized solutions and their respective initial conditions, and conclude with the prospects for future quasi-isodynamic optimization.
