mathematical model of the collector. The angular acceptance of the unit was measured by measuring the thermal output as a function of solar elevation. The results indicated that small imperfections in the shape of the collector did not have significant consequences. A test of the angular acceptance of prototype mirror sections fabricated by various methods has been devised. This apparatus is simple to use in the laboratory, and does not require construction of a complete collector. The optical design of a Compound Parabolic Concentrator with a fin receiver is presented in the report, and the relationships for reflector area and reflector height are given for this geometry. This geometry is of interest because of the decreased need for insulation and the reduction in the amount of metallic absorber needed. Show Less
