A cryostatic vessel 12 is radially interconnected inside a tubular thermal shield 18. A shield first endplate 20 includes a plurality of spacers 30 which are disposed in axial abutment with a corresponding first endplate 14 of the vessel during assembly. A shield second endplate 22 is disposed in axial abutment against an opposite end of the shield, and includes alignment holes 36 receiving corresponding alignment pins 32 extending from an opposite endplate 16 of the vessel. The spacers maintain a predetermined clearance between the endplates of the vessel and shield which clearance is precisely maintained upon fixedly joining both shield endplates to the shield.

1. A cryostat comprising:a cryostatic vessel having first and second endplates at axially opposite ends thereof, said second endplate having a plurality of temporary alignment pins extending therefrom; a tubular thermal shield surrounding said vessel, and having first and second endplates at axially opposite ends thereof, said shield second endplate having a plurality of alignment holes receiving respective ones of said pins; a plurality of radial mounts suspending said vessel inside said shield at both ends thereof; a plurality of axial mounts interconnecting said vessel inside said shield; and a plurality of circumferentially spaced apart temporary spacers disposed between said vessel first endplate and said shield first endplate; wherein said temporary spacers and said temporary alignment pins are adapted to be removed from said shield first endplate and said vessel second endplate, respectively after said axial mounts are finally adjusted, and said shield first endplate and said shield second endplate are fixedly joined to said shield.
