Abstract:
Formation of a wave-front pattern accompanied by an electrostatic ion-cyclotron instability driven by electrons drifting along a magnetic field is investigated by two-and-half dimensional particle simulations. A clear spatial pattern appears as the ion cyclotron wave grows due to the instability. When the electron stream is uniform in the system, an obliquely intersected stripe is formed. When the stream has a bell-shaped pattern across the magnetic field, a V-shaped stripe pattern appears. The wave fronts have small angles with the magnetic fie]d lines and propagate from the high-stream region to the low-stream region.
