Techniques of Multiple-layer Insulation Ⅲ

– Working Process and Vacuum Techniques for Multiple-layer Insulation –

Abstract

Multiple-layer Insulation (MLI) is essential for cryogenics. Without MLI, it is impossible to attain cryogenic temperatures. MLI is one of vacuum thermal insulations that requires a high vacuum to obtain enough performance. MLI working process is important to get high thermal insulation performance of a cryogenic system/device. In order to attain and maintain a good vacuum for MLI, a baking process is required to reduce the Out gas. Reduction of the Out gas is extremely important for maintaining a good insulation vacuum.
