The AFRL Space Vehicles Directorate has installed a TS Space quad source solar simulator (Unisim 100) for characterization of advanced space photovoltaics. The system has four independent light sources (one metal halide lamp and three tungsten lamps) with optical filters roughly aligned to the current set of inverted metamorphic (IMM) 4J bandgaps (1.88eV, 1.42eV, 1eV, 0.7eV). The system has been operational for several months, and during that time a detailed characterization of the units operating parameters, including spatial uniformity, temporal stability and measurement plane sensitivity, has been performed. Data will be presented on these characteristics, with comparison to similar tests performed on a Spectrolab X-25 simulator, as well as on operational experiences in characterizing advanced devices.
