ANALYSIS OF PLASMA GENERATORS.
Abstract
This report is an evaluation of existing plasma generators in terms of their capability of providing experimental data, useful to the determination of telemetry plasma sheath interactions, and the formulation of techniques for testing telemetry under simulated re-entry conditions. The plasma characteristics of typical re-entry plasmas were calculated to delineate the range of parameters to be simulated. Electromagnetic wave propagation and antenna effects were reviewed to establish the parameters to be studied in the experimental tests. The plasma generators studied were: radio frequency plasma generators, low density pma generators, glow discharge tubes, shock tubes, electromagnetic shock tubes, hypervelocity impulse tunnels, shock tunnels, arc heated wind tunnels, and free flight ranges. These were categorized according to electron concentration, collision frequency, operating pressure, cost, geometric size, test time, and frequency of operation. Tests were formulated to evaluate reflection, and attenuation effects, information rate, modulation parameters, antenna breakdown, and also complete systems. (Author)
