A New 75 kW High-Flux Solar Simulator for High-Temperature Thermal and Thermochemical Research

A new high-flux solar simulator capable of delivering up to 75 kW of continuous radiative power at peak fluxes exceeding 4250 kW/m(2), is operational at the ETH-Zurich. Its optical design and performance are described. This unique facility serves principally as an experimental platform for investigating thermal and thermochemical processes at temperatures up to 3000degreesK.
