Abstract
Experimental results for various multilayer insulation (MLI) systems are summarized for two sizes of tank calorimeters. The cold side boundary temperature was normal boiling point (NBP) helium (4.2 K) with hot boundaries between 30 and 130 K. Heat rate data were obtained for double aluminized Mylar (DAM) and double goldized Mylar (DGM) radiation shields and for a wide variety of net spacer materials. The data indicate the temperature regimes in which the application of MLI to the tank reduces heat rates below the rate for a low emissivity surface without MLI. These data are useful in the design of long-life systems which incorporate low-temperature vapor-cooled shields, for example, He-II and solid hydrogen cryostats for long-life space operation.
