摘要：

We consider the Child-Langmuir asymptotics11,5 of a monodimensional electron beam flowing through a background of positive ions of constant density n(D). We extend the results valid for electron beams in the vacuum11,5 to the case of small n(D)'s. Large n(D)'s strongly modify the phase portrait of the characteristics of the Vlasov-Poisson equation and yield a different result.
