• The theoretical and numerical investigation of the dynamical processes of non- monotonic double layers (NDL's) with potential depression (or hump) at the low (or high) potential side are presented. In order to obtain the NDL acceleration and growth rate from a momentum balance equation, a phase space hole concept in the negative effective mass term is used. In order to compare with the theory of the NDL dynamics and simulations, the evolution of NDL' s in a one-dimensional Vlasov plasma with injection of current-carrying plasma from both ends is investigated by one-dimensional bounded particle-in-cell code XPDP1, which is the workstation version of the one-dimensional electrostatic bounded-plasma code PDW1 [J. Comput. Phys. 80 (1989) 253]. The theoretical acceleration and growth rate are in good agreement with the results of simulations.
