论文摘要
众所周知，湍流运输会限制当今优化恒星的血浆限制。为了解决这个问题，提出了一种在这种设备中强烈抑制湍流的新方法，即超热颗粒的谐振波颗粒相互作用 - 例如，来自离子 - 循环 - 克洛特rot子 - 频率（ICRF）加热 - 具有湍流驱动的微稳定性，例如湍流微稳定性，例如离子机能诸如诸如诸如诸如ION-ION-ION-ION-ION-ION-EIN-EIN-eion-permature gradection gradeigent（Isg）gradient（Isge）。通过分析理论和大规模陀螺仪模拟证明了这种机制的有效性，这表明总体湍流减少了80美元\％$。这些结果具有新的且仍未开发的恒星场景的希望，并具有增强的限制和提高的性能，这对于在未来设备中实现燃烧的等离子体至关重要。
Turbulent transport is known to limit the plasma confinement of present-day optimized stellarators. To address this issue, a novel method to strongly suppress turbulence in such devices is proposed, namely the resonant wave-particle interaction of supra-thermal particles - e.g., from ion-cyclotron-resonance-frequency (ICRF) heating - with turbulence-driving microinstabilities like ion-temperature-gradient (ITG) modes. The effectiveness of this mechanism is demonstrated via analytic theory and large-scale gyrokinetic simulations, revealing an overall turbulence reduction by up to $80\%$. These results hold the promise of new and still unexplored stellarator scenarios with enhanced confinement and improved performance, essential for achieving burning plasmas in future devices.
