摘要:
It is demonstrated through a time‐dependent particle simulation that an extended sheath forms spontaneously when a nonneutral plasma reflects from a potential barrier. An analytical description shows that extended sheaths develop when the flow velocity is smaller than the Gould‐Trivelpiece speed, hence a generalization of the Bohm‐condition to nonneutral systems is obtained. © 1995American Institute of Physics
