High Altitude Plasma Effects

Abstract

The principal results of the program to simulate ionospheric modification field experiments in the QUIPS device are reviewed. The main conclusions are: By linear mode conversion electromagnetic waves (EMW) propagating in the inhomogeneous laboratory plasma produced very intense electron plasma waves (EPW) (orders of magnitude above the EMW) propagating along the density gradient. Unanticipated by conventional theory, the linearly converted EPW was the lowest threshold pump of the parametric instability. In square wave operation, at the turn-off and turn-on of the EMW pump, the ponderomotive force due to the electrostatic field of the linearly converted EPW produced a large pulse of density perturbation, proportional to incident power (i.e., without threshold), which propagated away from the plane of reflection of the EMW.
