摘要
磁约束核聚变是解决能源危机的最佳方法,托卡马克已经成为受控热核聚变最有可能成功的装置。高约束模式(H模)下自发产生的边界局域模(ELM)在爆发时携带的大量粒子和能量会对装置的第一壁材料造成很大的损坏。因此,本文在分析H模及ELM的基本物理图像和特征基础上,利用BOUT++模拟程序对ELM进行了初步分析,结果发现,抗磁效应能很好地抑制ELM不稳定性的增长率。
Magnetic confinement fusion(MCF)is considered as the best way to solve energy crisis and tokamaks become the most hopeful devices of magnetic confinement fusion.The edge-localized modes(ELM)are often excited in a highconfinement mode(H-mode)plasma,and energy and particles carried by ELM burst will severely damage the first-wall of fusion device.Basic pictures and characteristics of H-mode of ELM are shown in this paper,and preliminary studies using BOUT++simulation program for analyzing ELM are presented.Simulation results indicate that the diamagnetic effects can mitigate the linear growth rate of ELM effectively.
