Abstract

Current-voltage characteristics of asymmetric double probes have been measured in hydrogen plasmas. It has been found that up to a critical ratio of the areas, a part of the probe characteristic in the neighbourhood of zero voltage is symmetric with respect to a symmetric point. Above that critical ratio, the characteristic approaches that of a single probe. The true single probe characteristic can be obtained only if the area ratio is much larger than the above critical value. The aim of this paper is to investigate the validity of this and prove experimentally the critical limit in an actual plasma.
