AN INVESTIGATION OF THE RADIAL DISTRIBUTION OF LIGHT FROM AN ARGON DISCHARGE.
Abstract
The light intensity distributions in the positive column of a cylindrical argon discharge were observed to determine the radial distributions of the emitters of this detected light. A collimated beam of light originating in the discharge was observed using the 1P28 as the detector. The transformation of the data from the observed intensity profiles to radial distributions was accomplished by the use of a new method. It was observed that (1) the normalized radial distribution of emitters shows a regular variation with greater constriction at lower currents (constant pressure) or higher pressure (constant current); (2) as currents increased and/or pressure decreased, the distribution of emitters approached the zero order Bessel function distribution; and (3) no significant variation of radial emitter distribution could be associated with the presence or absence of striations.
