Abstract
The invention provides a cryostat whose components are detachably connected to each other. Each of the tanks (1, 7) is equipped with only one radial pipe (15 or 16) arranged at the end of the tank (1, 7). Each of the inner components (3, 7) is provided, at its end neighboring the pipe (15), with a detachable cover (5, 9), and provided with a recess (31, 71) into which the pipe (15) can be introduced from the end of the component. The jacket (11) is divided in a plane neighboring the pipes (15, 16). The shorter section (45) comprises a recess for the pipes (15, 16) passing through the jacket, and a connection for a tower (19) enclosing the pipes. This makes it possible to do without any welded connections between those sections of the concentrically arranged components which pass through each other. These welded connections, which heretobefore were necessary, led to structures whose individual components could not be separated from each other without destructive manipulations and which further provided the disadvantage that the heat developed by the welding operations had detrimental effects on the application of a super-insulation.
