Author(s): Sergey V. Bazdenkov and T. Sato Title: On a Ballistic Method for Double Layer Regeneration in a Vlasov-Poisson Plasma Date of publication: June 1992 Key words: double layer, double layer regeneration, ballistic effect, bump-on-tail distribution, nonlinear plasma response. Abstract: Double layers generated by a current-driven instability are usually alive short time and destroyed by emitting solitons and other nonlinear waves. It is analytically shown that they can be regenerated in one-dimensional Vlasov-Poisson plasma system where the upstream velocity distribution is swiftly heated to restore an unstable condition in the downstream region due to ballistic deformation.
