Multilayer Insulation with Applications in Cryogenic Equipments

Abstract

It is well known the fact that the most important problem in the cryogenic systems is the heat leak and that study is about the major heat leak of the system, which is the termal radiation.

Our purpose is to find the most suitable shielding method with Multi-Layer Insulation (MLI), using higly reflective foils of aluminium for the reflecting surfaces, interleaved with spacers to minimize conduction.

The project proposes theoretical and applied research on methods of cryogenic cooling and control of heat transfer through multilayer thermal insulation at low temperatures and very low (including liquid helium), with applications in detritiation of heavy water and cooled superconducting electromagnetic fusion facility but in general the thermal insulation industry. By bringing to the forefront of research areas of great current and impending importance for applications, making use of opportunities related to the existence of the partnership and cryogenic installations through a systematic approach to natural base of a multidisciplinary research team, to ensure optimum progress of the project.
