The Directly Irradiated Annular Pressurized Receiver (DIAPR) is a volumetric (directly-irradiated) windowed cavity receiver, designed for operation at a pressure of 10–30 bar, exit gas temperature of up to and aperture radiation flux of up to This paper presents test results obtained under various irradiation conditions and flow rates. Inlet aperture flux was up to exit air temperatures of up to were obtained, while operating at pressures of 17–20 bar. Estimated receiver efficiency in these tests was in the range of 0.7–0.9. The absorber and window temperatures were below the permitted maximum, indicating that higher air exit temperatures are possible.
