Abstract :
Two-dimensional particle-in-cell simulation in a cylindrical geometry shows that the vortex formation and merging of a magnetically confined pure electron column are controllable with rotating-wall electric fields. With an optimized frequency, the vortex merging time can be extended longer than that without rotating fields.
