Abstract

Abstract A support structure for transmitting large forces between a superconducting magnet winding which is cooled to a very low temperature and an abutment which is at a higher temperature level and takes up the forces, especially in an energy storage device, contains support elements which point, at least approximately, in the direction of force transmission and between which stiffening elements are attached, and at least one sheet-like heat shield. This support structure has high buckling stiffness and nevertheless results in low losses due to heat transfer by making all support elements and all stiffening elements of the support structure of a really extended design formed in a honeycomb-like structure and using at least one plane of stiffening elements to form the heat shield which is kept at a predetermined intermediate temperature by means of a coolant conducted through cooling canals. In the stiffening elements of the heat shield parts of a material with high thermal conductivity such as wires of copper, are advantageously arranged.
