Abstract : Charged particle measurement to techniques have been investigated regarding their capabilities for absolute and relative gravity measurements. Force-balance particle techniques, particle pendulum approaches and freeparticle methods have been evaluated analytically and experimentally in relation to gravity measurement requirements. Free-particle bouncing and recapture methods were determined to be the most appropriate with experiments demonstrating general performance feasibility. Additional development is required in order to achieve suitable free-particle instrumentation techniques. Research could then be conducted to evaluate and minimize error sources. It is concluded that free-particle relative gravity measurement capabilities should be evaluated before absolute gravity techniques are developed. (Author)
