Abstract
A cryostat arrangement (1), with a vacuum container (2) and an object (4) to be cooled, is provided, wherein the object (4) to be cooled is arranged inside the vacuum container (2) comprising a neck tube (8) leading to the object (4) to be cooled. A closed cavity (9) is formed around the cooling arm (10) of a cold head (11), wherein the cavity (9) in normal operation is filled at least partly with a first cryogenic fluid (34), and wherein a first thermal coupling component (15) is provided for the thermal coupling of the first cryogenic fluid (34) in the cavity (9) to the object (4) to be cooled. The cryostat arrangement (1) further comprises a pump device (14), to which the cavity (9) is connected, and with which the cavity (9) is configured to be evacuated upon failure of the cooling function of the cold head (11). Various cryostat configurations are provided.
