ABSTRACT:
A cryostat (1) in particular for the acceptance of a superconducting magnet coil (2) for NMR or ICR measurements, exhibits a central vessel (3) for fluid helium which by means of holding means (4), preferentially thin-walled suspension tubes, is mechanically connected to, preferentially is suspended from, the inside of a closed outer jacket (5) of the cryostat (1) whereby the holding means (4) are in good thermal contact, via good thermally conducting tube-shaped connecting elements (6) which completely surround the holding means (4), with a shell (7) surrounding a central vessel (3), the shell (7) being held, in particular, at the temperature of liquid nitrogen, and the thermally good conducting tube-shaped connecting elements (6) being configured to be mechanically flexible. In this fashion, the central vessel (3) is mechanically decoupled from the shell (7) which is thermally connected to the holding means (4) of the central vessel (3). In this fashion, when the shell (7) is tipped, a motion of the central vessel (3) in particular of the magnet coil (2) located therein is avoided. (FIG. 1b)
