Abstract
There is provided a cryogenic link and a method of installing a cryogenic link. The cryogenic link comprises: a core and a cryostat. The cryostat comprises a flexible sleeve around the core and is configured to maintain a temperature of the core at a cryogenic temperature. The cryostat further comprises spacing means configured to maintain a spacing between the core and the flexible sleeve during expansion and contraction of the core. The flexible sleeve is suitable for fixing to an external structure at a plurality of fixed points, where each of the plurality of fixed points is separated by a distance, and a length of the cryogenic link between at least one pair of fixed points is greater than the distance between that pair of fixed points.
Claims19
A cryogenic link comprising:
- a core;
- and
- a cryostat comprising a flexible sleeve around the core, the cryostat configured to maintain a temperature of the core at a cryogenic temperature, and spacing means configured to maintain a spacing between the core and the flexible sleeve during expansion and contraction of the core,
- wherein:
- the flexible sleeve is suitable for fixing to an external structure at a plurality of fixed points, each of the plurality of fixed points separated by a distance, and a length of the cryogenic link between at least one pair of fixed points is greater than the distance between that pair of fixed points, and
- wherein at least one of the plurality of fixed points is configured to allow movement of the cryogenic link in any direction tangential to the cable direction at the at least one of the plurality of fixed points.
A method of installing a cryogenic link having a core, and a cryostat comprising a flexible sleeve around the core configured to maintain a temperature of the core at a cryogenic temperature, the cryostat comprising spacing means configured to maintain a spacing between the core and the flexible sleeve during expansion and contraction of the core,
- the method comprising:
- arranging the cryogenic link to run between a plurality of fixed points each of the plurality of fixed points separated by a distance, wherein a length of the cryogenic link between at least one pair of fixed points is greater than the distance between that pair of fixed points, and wherein at least one of the plurality of fixed points is configured to allow movement of the cryogenic link in any direction tangential to the cable direction at the at least one of the plurality of fixed points;
- and
- fixing the flexible sleeve of the cryogenic link to each of the plurality of fixed points.
