摘要: The effect of the conducting boundary on temporal evolution diocotron instability a planar and cylindrical electron flow in uniform magnetic field has been investigated by using two-dimensional particle-in-cell (PIC) simulations for various boundary-wall locations. growth rates measured PIC match well those calculated analytic linear theories. approach boundaries to was observed not only reduce rate but also change mode structure. nonlinear behaviors lead phase-locking configuration generate vortices.
