Non-neutral electron plasmas confined with a nested potential in a uniform magnetic field

Abstract

Confinement properties of a non-neutral electron plasma are investigated with a nested potential in a uniform magnetic field. The main result is that the positive plug potentials can be maintained by applying an appropriate resonant RF field to the plug potentials. Since the nested potentials in a magnetic field can confine both positive and negative charged particles simultaneously, it is expected that the technique will be applied to study electron–positron plasmas experimentally.
