Field‐error induced transport in a pure electron plasma column

The long confinement times achieved in experiments on pure electron plasmas are explainable in terms of the conservation of canonical angular momentum in azimuthally symmetic systems. A low‐density, pure electron plasma is considered, and the effect of disrupting the system’s symmetry by introducing...

Description
Summary:The long confinement times achieved in experiments on pure electron plasmas are explainable in terms of the conservation of canonical angular momentum in azimuthally symmetic systems. A low‐density, pure electron plasma is considered, and the effect of disrupting the system’s symmetry by introducing a small, magnetic field error is investigated. It is found that this external perturbation can resonantly drive low‐frequency waves that couple back to the field error and produce a change in the plasma’s angular momentum. This results in changing the radius of the column.
