candidates for reflector panel design concepts, including materials and configurations, were identified. the large list of candidates was screened and reduced to the five most promising ones. cost and technical factors were used in making the final choices for the panel conceptual design, which was a stiffened steel skin substrate with a bonded, acrylic overcoated, aluminized polyester film reflective surface. computer simulations were run for the concentrator optics using the selected panel design, and experimentally determined specularity and reflectivity values. intercept factor curves and energy to the aperture curves were produced. these curves indicate that surface errors of 2 mrad (milliradians) or less would be required to capture the desired energy for a brayton cycle 816 c case. two test panels were fabricated to demonstrate manufacturability and optically tested for surface error. surface errors in the range of 1.75 mrad and 2.2 mrad were measured
