Test and evaluation results for the heliostats and beam characterization system at the 10 MW/sub e/ Solar Thermal Central Receiver Pilot Plant are described in this report. Southern California Edison operated and maintained the plant during the five years covered by this evaluation. Therefore, the results represent what can be expected from a large number of heliostats that are operated over a long period of time in a power plant environment. The heliostats and beam characterization system were evaluated for their ability to meet performance and survival requirements. Heliostat evaluation results are reported for mirror soiling rates, mirror corrosion, wind loads, availability, maintenance requirements, tracking accuracy, beam quality, component temperatures, and operating power requirements. The heliostat beam characterization system accuracy is given for the measurement of beam quality, heliostat tracking accuracy, and power in the reflected beam. The heliostat technical specifications and design description are provided, and a detailed design description of the beam characterization system is included. 41 refs.
