ABSTRACT:
A cryostat for a magnetic resonance magnet is provided comprising a cylindrical helium vessel concentrically situated in the cryostat. A first cylindrical shield is situated in the cryostat surrounding the first shield. A plurality of tubular struts are affixed to both the helium vessel circular end faces and the second shield. The tubular struts are circumferentially spaced and extend radially, parallel to the end shields of the helium vessel. The struts support the second shield spaced away from the helium vessel. Plate means are circumferentially spaced about the circular end faces of the first shield and affixed thereto. The plates extend radially, parallel to the end faces of the first shield and affixed to the inner circular end faces of the second shield, supporting the first shield spaced away from the second shield.
