Abstract : This study was made to evaluate three new high-powered arc sources as possible radiation sources for a large modular solar simulator. The three sources are (1) the Vortex Stabilized Radiation Source developed by Giannini Scientific Corp.; (2) the Fluid Transpiration Arc; and (3) the High Intensity Carbon Arc. The radiation characteristics of the sources have been studied to determine the spectral properties of the radiation from each source, and to permit derivation of mathematical expressions for the radiance distribution of each source. A careful review of the nature of solar radiation and of the theory of energy transfer in optical systems has been conducted. On the basis of this review and the source radiance functions derived in the source study, several optical system concepts for solar radiation simulation have been synthesized and analyzed for use with each source. The optical concepts studied range from simple parabolic collimators and uncollimated projection modules to systems consisting of trains of conic section reflectors and modifications thereto.
