An insert based on a top-loading, fully welded stainless-steel design, with a special steel-copper weld is described. It has been developed explicitly for pumped helium cryostats, down to a temperature of about 1.2 K. The principal characteristics of this insert are a large high vacuum sample space, the absence of any cold seal, and the reliability and flexibility of use. Typical applications are optical/UV/x-ray photon counting experiments based on cryogenic detectors and the development of advanced heterodyne receivers using Superconductor-Insulator-Superconductor junctions as mixers in the millimeter and submillimeter regimes.Link to publication
