| Zusammenfassung |
| We studied the evolutions of double layers which appear after the magnetic
reconnection through two-dimensional electromagnetic particle-in-cell
simulation. The simulation results show that the double layers are formed in
the plasma sheet boundary layer after magnetic reconnection. At first, the
double layers which have unipolar structures are formed. And then the double
layers turn into bipolar structures, which will couple with another new weak
bipolar structure. Thus a new double layer or tripolar structure comes into
being. The double layers found in our work are about several ten Debye
lengths, which accords with the observation results. It is suggested that the
electron beam formed during the magnetic reconnection is responsible for the
production of the double layers. |
