N2 - We present the design and performance estimation of a 3 MWth beam down central receiver capable of providing concentrated solar energy to a particle-based thermochemical reactor operating at a thermal reduction (maximum) temperature of 1500oC. The configuration of this beam down optical system is unique in several ways including the positioning of the reactor near the top of the tower, the use of a flat tower reflector, and the absence of a terminal concentrator that is usually needed to increase the solar concentration ratio at the aperture for high temperature applications. Our baseline design for the beam down central receiver includes a 75 m tall tower with a North field of individually focused, ∼ 1 m2 heliostats that is capable of achieving an average concentration ratio in excess of 1,600 kW/m2 (suns) over an aperture that is 2 m in diameter with a peak flux in excess of 6,000 kW/m2.
