Feasibilities of Space Shuttle for Controlled Cerenkov-Echo Experiment

Comparisons are made between plasma experiments utilizing a space shuttle-mounted laboratory (spacelab) and using probe rockets (Aerobee type) traversing the magnetosphere, with emphasis on the study of controlled Cerenkov-echo phenomena with the aid of an onboard accelerator generating electron beams and/or ion beams. Elimination of wall effects under outer-space conditions, nonlinear interactions resulting from injection of beam pulses (shock wave, solitons, harmonic generation, parametric interactions, plasma turbulences), triggered emissions, artificial whistlers, micropulsations, fundamental and harmonic ion cyclotron waves and resonances, MHD waves, discrete emissions resulting from injection of electron or ion beams into the plasmasphere or magnetosphere are discussed. The expected course of a spacelab controlled Cerenkov-echo experiment is examined at length, with details on procedures and hardware.
