A specially modified Barnes Net Radiometer (Model 12-550) has been used to obtain information concerning the radiative losses from the EPRI/Boeing 1 MWth Bench Model Solar Receiver (BMSR). This solar receiver was tested at the DOE/Sandia Laboratories Central Receiver Test Facility on Kirtland Air Force Base in Albuquerque, New Mexico.
