标题： Energetics of kinetic reconnection in a three-dimensional null points cluster

摘要： 我们进行了包含多个磁零点的磁重联的三维粒子-网格模拟。 磁场能量转化为动能大约是传统哈里斯板配置的五倍。 在25次反向离子回旋频率期间，超过85%的初始磁场能量转移到了粒子能量中。 零点簇中的磁重联演化为三个阶段。 在第一阶段，激发了离子束，然后在第二阶段将部分能量回馈给磁场。 在第三阶段，磁重联发生在沿低磁场条纹形成的电流通道周围的许多小区域中。 零点中的磁重联表现出本质上三维的特征，没有二维对称性或电流片。 显示英文摘要

摘要： We performed three-dimensional Particle-in-Cell simulations of magnetic reconnection with multiple magnetic null points. Magnetic field energy conversion into kinetic energy was about five times higher than in traditional Harris sheet configuration. More than 85% of initial magnetic field energy was transferred to particle energy during 25 reversed ion cyclofrequencies. Magnetic reconnection in the cluster of null points evolved in three phases. During the first phase, ion beams were excited, that then gave part of their energy back to magnetic field in the second phase. In the third phase, magnetic reconnection occurs in many small patches around the current channels formed along the stripes of low magnetic field. Magnetic reconnection in null points presents essentially three-dimensional features, with no two dimensional symmetries or current sheets.
