Adiabatic Oscillations of the One-Dimensional SGEMP Boundary Layer

Adiabatic oscillations of the one-dimensional SGEMP boundary layer about equilibrium are described in a fluid approximation. The solution for monoenergetic emission normal to the surface is found and compared with a computer solution. Solutions for photoelectron emission with a cosine distribution for a monoenergetic and a linear times exponential energy distribution are also found. It appears that these latter solutions are not physically meaningful. If physically meaningful modes of oscillation do exist, for other emission configurations, they are probably stable.
