HELIUM CRYOSTAT FOR SQUID-MAGNETOMETER

摘要

Helium cryostat for squid-magnetometer is Dewar vessel made of glass fiber material, filled with helium, inside which squid-magnetometer is placed. In the wall of the vessel layer of material is mounted, this is polymer composition material that includes as filler flat-like glass fiber with possibility of formation of tortuosity of helium diffusion pass. Flat-like fiber is made with ratio of its width to thickness not smaller than 50.
