This patent describes an interface for a horizontal cryostat penetration insert for coupling a cryogenic refrigerator cold end to the cryostat penetration insert. The insert has an outer housing and a thermal radiation shield. The cryogenic refrigerator cold end has at least one stage. The interface comprises: an extension of the outer housing providing access to the interior of the housing; an extension of the thermal radiation shield into the housing extension; a first thermal contact means affixed to the end of the thermal radiation shield extension. The first thermal contact means defines a central aperture and provides heat conduction between the shield extension and the first contact; a second thermal contact affixed to the stage of the cryogenic refrigerator cold end to provide heat conduction from the second thermal contact means to the cryogenic refrigerator stage; and means for rotatably mounting the stage of cold end refrigerator in the housing extension, the second thermal contact means situated in the central aperture defined by the first thermal contact means.
