Cryostat configuration for keeping cryogenic fluids in at least one
cryocontainer (1) which is suspended on thermally insulating suspension
tubes (2) and/or suspension devices which are connected to an outer
jacket (3) of the cryostat configuration, wherein the at least one
cryocontainer (1) is centered relative to a container disposed further
outside, preferably the outer jacket (3), using at least three centering
elements (4) which are distributed about the periphery of the
cryocontainer (1), wherein one end (5) of each centering element (4)
abuts or is connected to the container disposed further outside,
characterized in that in at least one of the cryocontainers (1), each end
(6) of the centering elements (4) facing away from the outer jacket (3)
is connected to an actuator (7) which exerts a pressure or tensile force
on the respective centering element (4), and which is mounted to the
cryocontainer (1) at at least one contact point (A, A', B, B'), wherein,
through fixation of the actuator (7) to the cryocontainer (1) at the
contact point (A, A', B, B'), through thermal changes in size of the
cryocontainer (1), through thermal changes in sizes of individual
components of the actuator (7), and optionally through mechanical
translation, a mechanical tension is generated in the corresponding
centering elements (4) such that the centering elements (4) remain loaded
with a nearly constant pressure or tension, preferably in the range of
.+-.10% of the pressure or tension prevailing at room temperature and
irrespective of the temperatures within the cryostat configuration. This
yields a cryostat configuration which permits pressure centering without
overloading the centering elements.
