ABSTRACT:
A storage vessel for liquefied gas, especially liquefied helium and liquefied hydrogen intended to be stored at temperatures below about 30.degree.K, comprises inner and outer shells respectively at the liquefied-gas temperature and an ambient temperature, a radiation shield disposed between but spaced from the inner and outer shells and cooled by nitrogen or the like to a temperature between the storage temperature and ambient (preferably of the order of 70.degree.K), a filling of a particulate insulating material between the radiation shield and the inner shell, and a filling composed of a mixture of such insulating particles and reflective metal particles between the outer shell and the radiation shield. The spaces between the inner and outer shells, respectively, and the radiation shield are evacuated and the insulating material is preferably perlite. The metal particles may be aluminum or copper.
