论文摘要
描述了一种新的优化的准对称构型,具有改善能量粒子限制,减少湍流运输的3D成型和非谐振的移动能力的特性。本文中介绍的配置明确优化了用于准对称性,能量粒子限制,新古典限制和稳定性附近的稳定性。在优化后,对其在各种等离子体压力值下的能量颗粒传输,IdealmagnetoDrolnanic(MHD)稳定性以及离子温度梯度不稳定性引起的湍流转运方面评估了其性能。离散轴心的各种功绩限制数字的影响,包括能量粒子限制,通过生成用于构型的单丝线圈来确定。初步的分离分析表明,可以创建线圈,不会干扰外向热通量区域附近的vessel体积的膨胀,从而证明了运行非谐波分离的可能性。
A new optimized quasihelically symmetric configuration is described that has the desir-able properties of improved energetic particle confinement, reduced turbulent transportby 3D shaping, and non-resonant divertor capabilities. The configuration presented in thispaper is explicitly optimized for quasihelical symmetry, energetic particle confinement,neoclassical confinement, and stability near the axis. Post optimization, the configurationwas evaluated for its performance with regard to energetic particle transport, idealmagnetohydrodynamic (MHD) stability at various values of plasma pressure, and iontemperature gradient instability induced turbulent transport. The effect of discrete coilson various confinement figures of merit, including energetic particle confinement, aredetermined by generating single-filament coils for the configuration. Preliminary divertoranalysis shows that coils can be created that do not interfere with expansion of thevessel volume near the regions of outgoing heat flux, thus demonstrating the possibilityof operating a non-resonant divertor.
