摘要：

A trapped pure electron plasma column can be unstable if the plasma column is contaminated by a small number of oppositely charged ions. This instability was analyzed by Levy, Daugherty, and Buneman [Phys. Fluids, 12, 2616 (1969)] for the case of trapped ions. The instability is analyzed here for the case of untrapped ions. The analysis is inherently nonlinear, and growth results from averaging over the ion initial conditions. Several significant differences exist between the two cases, including, for the latter, growth over a much broader parameter region and linear (secular) rather than exponential growth. The predictions of the analysis are compared to the results from a recent experiment on the instability.
