Summary

In an experiment using superfluid helium, a successful method has been developed for sealing a G-10 to G-10 interface within the superfluid which satisfies the following requirements: 1) provision for a very good (though imperfect) thermal barrier to heat flow; 2) easy disassembly; and 3) allowance for significant roughness or mismatch between the mating surfaces. Test results using a variety of sealing methods and materials are presented; these reveal that a combination of furniture wax applied to the G-10 surfaces and a subsequent epoxy seal between the waxed surfaces provides the best means for satisfying the requirements.
