Résumé

Perforated multilayer insulation (MLI) blanket systems are targeted for large-scale cryogenic facilities. Space applications and particle accelerators are two fields concerned with thermal shielding of cryogenic devices. Because radiation heat transfer varies with T4, heat transfer in the range of 300 to 77 K is dominant even for devices operating at temperatures as low as 2 K. Systems operating under conditions of degraded vacuum levels are also a key consideration because of heat transfer by residual gas conduction. The results of an experimental study of a perforated MLI blanket system using a steady-state liquid nitrogen evaporation method are presented.
