A cryostat is provided comprising a closed cylindrical vacuum vessel and a helium vessel situated inside the vacuum vessel. The helium vessel has four mounting supports on either circular face of the helium vessel, with two supports on the upper portion and two supports on the lower portion. Eight composite straps are provided with one end of each of four of the straps rotatably mounted to each of the mounting supports on each end face of the helium vessel. The other end of the straps are mounted through a clevis arrangement to the helium vessel. The straps on each face are parallel to the circular end faces of the vacuum vessel and the helium vessel. The straps symmetrically located about the vertical and horizontal axes of the helium vessel. The radial suspension provided does not move the axial centerline of the helium vessel relative to the axial centerline of the vacuum vessel when the temperature of the cryostat varies.

Radial cryostat suspension system

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.
