一种新的优化准螺旋对称配置，具有改善高能粒子约束，减少湍流transportby3D整形，和非共振偏滤器的能力所需的性能。本文中提出的配置是明确的优化准螺旋对称性，高能粒子约束，新经典约束和轴附近的稳定性。优化后，configurationwere评估其性能方面的高能粒子传输，理想的磁流体动力学（MHD）的稳定性，在各种值的等离子体压力，和离子温度梯度不稳定性引起的湍流运输。离散线圈对各种约束品质因数的影响，包括高能粒子约束，是通过产生单灯丝线圈的配置来确定的。初步偏滤器分析表明，可以创建线圈，不干扰膨胀的容器体积附近的地区传出的热通量，从而证明了操作的可能性非共振偏滤器。
英文摘要：
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.
