Effect of plasma properties on magnetic bubbles

In this work, a three-dimensional hybrid simulation program is used to investigate the process of explosion and expansion large number thermal debris ions in low density background plasma. By quantitatively calculating variation magnetic bubble constraint motion cloud, studied are influences plasma charge density, ion atomic weight, charge-mass ratio fragment on bubble. The results show that has an important effect cloud. early stage cloud expansion, weight little but it affects movement at later time. When small, radius gyration larger than radius, small so cannot restrain large, smaller radius. If condition, slightly affected by ions, only subsequent evolution system influenced. prominent influence
