Summary

In a previous paper we developed a quasineutral, one-dimensional fluid model of electrostatic shocks which, given a plasma model, allowed us to relate parameters describing the plasma to those defining shock solutions. Here we consider a plasma model consisting of warm downward streaming electrons, cool Boltzmann electrons, cold upward streaming ions and hot Boltzmann ions. We show that there is little difference between having a finite temperature in the electron beam and leaving the beam cold. This implies a greater utility for the cold electron beam model considered in an earlier paper, and adds weight to the idea that the smaller amplitude electrostatic shocks seen in conjunction with ion beams are nonlinear ion acoustic modes.
