摘要:
The cryostat thermal insulation of the stellarator Wendelstein 7-X (W7-X) is being built by MAN DWE and its main sub-contractor Linde AG Development and engineering of the plasma vessel (PV) insulation is finished and production is starting. The complex geometry and narrow gaps to the superconducting coils require innovative solutions concerning the multi-layer insulation (MLI) as well as the shield and its supports. Crinkled Al-coated Kapton (R) foils with glass paper spacers were chosen as MLI, and the shield consists of epoxy-glass resin containing copper meshes for temperature equalisation. Shield supports are made of Torlon (R) which exhibits extremely low thermal conductivity and good mechanical strength.
