摘要

首次对托卡马克边缘相关参数的高频离子伯恩斯坦波湍流进行了六维-弗拉索夫计算机模拟,结果显示其传输与亚拉莫尔频率陀螺动能湍流相当。磁化等离子体湍流研究局限于陀螺动能近似的惯例可能并非基于物理学,而只是由于计算成本造成的实际限制。由于边缘湍流对磁约束等离子体的约束特性有重大影响,因此破译湍流输运至关重要。尽管计算成本很高,但进行 6D 动力学模拟对于了解我们当前模型的局限性至关重要。

High-Frequency Nongyrokinetic Turbulence at Tokamak Edge Parameters
First of a kind 6D-Vlasov computer simulations of high frequency ion Bernstein wave turbulence for parameters relevant to the tokamak edge show transport comparable to sub-Larmor-frequency gyrokinetic turbulence. The customary restriction of magnetized plasma turbulence studies to the gyrokinetic approximation may not be based on physics but only on a practical constraint due to computational cost. Deciphering turbulent transport is crucial since edge turbulence significantly influences the confinement properties of magnetically confined plasmas. Despite the high computational costs, performing 6D kinetic simulations is essential for understanding the limitations of our current models.
