Abstract

The paper analyzes the radiative thermal transfer in a liquid helium cryostat with liquid nitrogen shielding. A infinite plane walls model is used for demonstrating a method for lowering the radiative heat transfer and the numerical results for two such systems are presented. Some advantages concerning the opportunity of using semi-transparent walls are analytically and numerically demonstrated.
