Active Probing of Space Plasmas

Abstract

During the course of the research period our efforts were focused on the following areas: 1) An examination of stochastic acceleration mechanisms in the ionosphere; 2) A study of nonequilibrium dynamics of the coupled magnetosphere - ionosphere system; and 3) Laboratory studies of active space experiments. Reprints include: Dynamics of charged particles in the near wake of a very negatively charged body -- Laboratory experiment and numerical simulation; Laboratory study of the electron temperature in the near wake of a conducting body; New model for auroral breakup during substorms; Substorm breakup on closed field lines; New model for substorm on sets -- The pre-breakup and triggering regimes; Model of the westward traveling surge and the generation of Pi 2 pulsations; Ionospheric electron acceleration by electromagnetic waves near regions of plasma resonances; Relativistic particle acceleration by obliquely propagating electromagnetic fields; Some consequences of intense electromagnetic wave injection into space plasmas. Keywords: Electron acceleration; Wave particle interaction; Substorm dynamics; Spacecraft interactions.
