Description
Summary:In crossed-field devices, Brillouin flow is regarded as the prevalent equilibrium flow 1 . One-dimensional (1-D) theory and particle-in-cell (PIC) simulations demonstrated the universality of the near-Brillouin (nB) state, which corresponds to Brillouin flow superimposed upon a turbulent background 2,3 . The collapse of cycloidal flow to nB flow occurs for sufficiently high injection current density J^{2} . This transition is also sensitive to external perturbations, such as superimposing a small AC voltage on the gap 2 or adding a small series resistance 3 .
