Abstract

This paper describes a new technique for greatly reducing the evaporation from multiple-layer-insulated dewars, especially those containing helium or hydrogen. This is done by using the refrigeration of the escaping vapor to a far greater extent than heretofore practical. To do this, a large number of vapor-cooled shields are used to isolate the inner vessel from the environment. In both number and design these shields differ from previour efforts. Accordingly, the term “multishielding” has been coined to describe the resultant system.*
