V-shaped dc potential structure caused by current-driven electrostatic ion-cyclotron instability

摘要

It is first demonstrated that a V-shaped de potential structure is created by a current-driven electrostatic ion-cyclotron instability by means of an open two-dimensional particle simulation model. A positive de potential difference along magnetic field lines is generated by anomalous resistivity caused by the ion-cyclotron instability. In the direction across the magnetic field lines, the de potential rises from the high-current region to the low-current region.
