论文摘要
M. Cole等人在XGC中针对XGC中实现的简化Delta-F混合变量/下拉电磁模拟算法。 [物理。等离子体28，034501（2021）]已被推广到总-F电磁算法，该算法首次包括具有中性粒子回收，湍流和新古典物理学的转移磁几何形状中的边界等离子体。 Delta-F混合变量/撤回电磁基于Kleiber和Mischenko等人的开创性工作。 [R. Kleiber等人，物理。等离子体23，032501（2016）; A. Mishchenko等，计算。物理。社区。 238，194（2019）]。电磁示范模拟是在DIII-D样H模式边界等离子体中进行的，包括相应的比较静电模拟，该模拟证实了电磁模拟对于对电子粒子的富裕程度更高的理解和热量传输所必需的，即使在磁性分离的宽敞的基座上，也是磁性脚的热传输。
The simplified delta-f mixed-variable/pull-back electromagnetic simulation algorithm implemented in XGC for core plasma simulations by M. Cole et al. [Phys. Plasmas 28, 034501 (2021)] has been generalized to a total-f electromagnetic algorithm that can include, for the first time, the boundary plasma in diverted magnetic geometry with neutral particle recycling, turbulence and neoclassical physics. The delta-f mixed-variable/pull-back electromagnetic is based on the pioneering work by Kleiber and Mischenko et al. [R. Kleiber et al., Phys. Plasmas 23, 032501 (2016); A. Mishchenko et al., Comput. Phys. Commun. 238, 194 (2019)]. An electromagnetic demonstration simulation is performed in a DIII-D-like, H-mode boundary plasma, including a corresponding comparative electrostatic simulation, which confirms that the electromagnetic simulation is necessary for a higher fidelity understanding of the electron particle and heat transport even at the low-beta pedestal foot in the vicinity of the magnetic separatrix.
