THE THERMOPHYSICAL PROPERTIES OF SOME MULTILAYER INSULATORS AT CRYOGENIC TEMPERATURES,

Abstract

The thermal conductivity coefficients for a number of multilayer insulations are given. The dependence of the value of the thermal conductivity coefficient on the pressure in the insulation space, at different compressions of insulation, was found. The coefficient of thermal conductivity was determined at the boundary temperatures 293 to 77.6 K, 293 to 20.4 K, and 293 to 4 K. The insulation was pressed from 1 g/sq cm up to 1000 g/sq cm. The pressure in insulation space varied from 0.00001 to 0.1 mm Hg. (Author)
