Experimental and Theoretical Studies into Pulse and Wave Phenomena in Plasmas.
Abstract
The report describes an investigation of methods for measuring the electron density in a reentry shaft. The methods include excitation of electroacoustic resonances and the observation of enhanced microwave breakdown. Good agreement is obtained between electron density profiles determined from electroacoustic resonance frequencies measured for a laboratory plasma and those calculated theoretically. If higher order resonances can be observed, departures of the profile from linearity can be obtained. Measurements of enhanced breakdown in a laboratory plasma under simulated reentry conditions suggest that this method should be feasible for some reentry plasmas. A hollow cathode plasma source was constructed in an attempt to simulate low altitude reentry plasmas. (Author)
