RADIATION TRANSMISSION THROUGH SHIELDING ARRAYS FOR LOW TEMPERATURE PUMPING SURFACES
Abstract
The results of an investigation to determine the amount of thermal radiation transmitted through two cryosurface configurations are presented. The configurations were composed of a 20 K cryosurface enclosed in a 77 K box with a test opening shielded by an optically dense array of 77 K cryosurfaces coated with Parson's black. Radiation at various levels of intensity was applied to the shielding array opening, and the heat load on the 20 K cryosurface imposed by energy transmitted through an array was measured. Heat transmission was also investigated with frost layers deposited over the Parson's black coating on the shielding surfaces.
