A compact cold-transfer apparatus for engaging and retrieving samples at liquid-helium temperatures (1.5--4 K), maintaining the samples at such temperatures for periods of hours, and subsequently inserting them in diverse apparatuses followed by disengagement, is described. The properties of several thermal radiation-insulating shrouds, necessary for very low sample temperatures, are presented. The immediate intended application is transportable target shells containing highly spin-polarized deuterons in solid HD or D{sub 2} for inertially confined fusion experiments. The system is also valuable for unpolarized high-density fusion fuels, as well as for other applications which are discussed.
