Description
The feasibility of propagating annular IREB in periodic permanent magnetic (PPM) field is studied. The PPM field is calculated first using the finite element magnetic method (FEMM). Then forces acting on IREB's electron in such magnetic field are analyzed by fluid model and the radial force equation in modified Mathieu function form is drawn. Finally a 2.5-D particle in-cell (PIC) simulation code is used to investigate the physical process of the IREB's propagation. It is found that the stable propagation for IREB is relative to not only the beam plasma density and its equilibrium position but also the magnetic field intensity and its space period length. The conclusion is drawn that several kA intense annular electron beam can propagate stably in a guiding PPM
