Claims

[Scope of utility model registration request]

(1) A holder that is fitted into the fixed tank which is the inside of the cryostat with a multi-vessel structure, and whose inner grip part can freely come into contact with the outer periphery of the tank, and a holder that extends in the outer radial direction from the holder. A plurality of spokes are formed by a thermally poor conductor,
The normal length of the spoke from the inner circumferential gripping part to the attachment part is longer than the normal distance from the inner peripheral surface of the fixation tank, which is the outside to which the attachment part is fixed, to the fixation tank, which is the inside. After being installed between the inner and outer fixed tanks in an extended state, the inner circumferential gripping part of the holding body is formed short by a dimension that becomes an abutment mark on the outer circumferential surface of the inner fixed tank by shrinkage when cooling. A cryostat spacer.

(2) A spacer for a cryostat according to claim 1, wherein the holding body and the spokes are integrally formed of FRP.

(3) A spacer for a cryostat according to claim 1, wherein the holder is formed into a perfect circular ring shape, and a pair of spokes extend in the diametrical direction of the holder.

(4) A spacer for a cryostat according to claim 1, wherein the inner peripheral gripping portion of the holding body is formed by a plurality of small protrusions.

(5) A cryostat spacer according to claim 1, wherein the holder is formed into a polygonal annular shape, and the spokes extend diametrically from the center of each side of the holder.
