论文摘要
充电颗粒的动量扩散是天体物理学，融合装置物理学和实验室等离子体中运输过程的重要机制。除了均匀的场动量扩散外，由于大规模磁场的聚焦效果，我们还获得了修饰项。在评估了修改术语后，我们发现它是由焦点特征长度和fokker-planck系数$ d_ {μμμ} $，$ d_ {μp} $，$ d_ {pμ} $和$ d_ {ppp} $确定的。结果表明，我们在这项工作中获得了新的二阶加速机制。
Momentum diffusion of the energetic charged particles is an important mechanism of the transport process in astrophysics, physics of the fusion devices, and laboratory plasmas. In addition to the uniform field momentum diffusion, we obtain the modifying term due to the focusing effect of the large-scale magnetic field. After evaluating the modifying term, we find that it is determined by the sign of the focusing characteristic length and the Fokker-Planck coefficients $D_{μμ}$, $D_{μp}$, $D_{pμ}$, and $D_{pp}$. It is shown that we get a new second order acceleration mechanism in this work.
