Cryothermal Measurements of Variable Emittance Coatings with Varied Amounts of Tungsten Doping

The purpose of this experiment is to determine how tungsten doping with lower phase transition temperature ranges affects a variable emittance coating’s performance in a cold space environment with internal heating. The results of this experiment will show how a variable emittance coating performs under cryostat testing conditions in order to determine its radiative cooling properties. By optimizing the performance of radiative cooling materials, energy originally used to provide thermal control can be preserved.
