Investigation of the reentrant linear magnetron using particle-in-cell simulation
(Color online) Schematic of the reentrant linear magnetron modeled by the two-dimensional MAGIC PIC code in the plane. The coordinate system is a Cartesian coordinate, and the length of the axis is considered as in the simulation.
