论文摘要
为了研究密度 - 泵出和电子热约束，使用全局总F陀螺仪XGC进行了谐振磁扰动（RMP），对DIII-D H模式边缘血浆（RMPS）的新古典和静电湍流传输的自谐模拟进行了模拟。考虑到线性两流体血浆响应，RMP字段是从扩展的磁氢动力学（MHD）代码M3D-C1导入的。通过考虑新古典和湍流物理，XGC模拟在RMPS下重现了实验观察到的边缘传输的两个关键特征：在基座区域的径向颗粒传输增加，足以考虑实验性泵送率，并抑制了边缘陡峭部分的电子热通量。在模拟中，由于与基座肩膀和向外的RMP相互作用，在电子电磁方向移动的模式的密度波动幅度增加，而电子温度波动幅度降低。
Self-consistent simulations of neoclassical and electrostatic turbulent transport in a DIII-D H-mode edge plasma under resonant magnetic perturbations (RMPs) have been performed using the global total-f gyrokinetic particle-in-cell code XGC, in order to study density-pump out and electron heat confinement. The RMP field is imported from the extended magneto-hydrodynamics (MHD) code M3D-C1, taking into account the linear two-fluid plasma response. With both neoclassical and turbulence physics considered together, the XGC simulation reproduces two key features of experimentally observed edge transport under RMPs: increased radial particle transport in the pedestal region that is sufficient to account for the experimental pump-out rate, and suppression of the electron heat flux in the steepest part of the edge pedestal. In the simulation, the density fluctuation amplitude of modes moving in the electron diamagnetic direction increases due to interaction with RMPs in the pedestal shoulder and outward, while the electron temperature fluctuation amplitude decreases.
