Abstract

Within a cryostat housing (17), an antenna device (7) having an antenna (16) to be cooled by a cryogenic medium (M). The cryostat housing includes a cold head (15) of a pulse tube cooler, whose cold part (20), which is at a low temperature (TT), is thermally coupled to the antenna (16). The coupling can take place via a dielectric thermal contact member (27).
