A Novel 20 KW Solar Simulator Designed for Air Pollution Research

An atmospheric chamber facility for the study of photochemical air pollution at ambient pollutant concentrations has been established at the Statewide Air Pollution Research Center of the University of California, Riverside.* The facility consists of two environmental chambers and a 20 KW solar simulator. This paper describes the properties and detailed performance characteristics of the solar simulator, including beam intensity, spectrum, uniformity and collimation. The simulator was designed to the special requirements of the SAPRC facility, and subsequently built and tested by the Aerospace Controls Corporation.
