STUDY OF RADIATION FROM VORTEX STABILIZED ARCS,

Abstract

Testing of space vehicles in ground space environmental facilities requires simulation of solar radiation as one important parameter. Solar radiation simulators in-being today utilize comparatively small scources such as carbon arc, mercury, mercury-xenon and xenon short arc lamps of power levels between 2.5 and 15 kw. The purpose of this study was to determine the radiation properties of the vortex stabilized arc plasma using the inert gases in a closed gas recirculating system. It was found that high intensity, 10 kw to 60 kw, vortex arcs radiate in an ultraviolet peaked continuum with relatively weak line radiation superimposed and largely confined to the infrared. Data on spectral power distribution, micro-radiancy, total radiant power and its spatial distribution are presented. The vortex arc is essentially cylindrical, but its shape and the spatial distribution of its radiation can be modified by electrode design to better match a selected optical system. (Author)
