Abstract
In large scale superconducting technical devices, it is often necessary to transmit large forces from low temperature to room temperature. The thermal losses caused by the cryogenic structure essentially determine, in some cases, the efficiency of the total superconducting system. Therefore these losses have to be minimised. This can be done in two ways:
-
(1)
constructively: with distances between the temperature levels as large as possible and a thermal conducting cross-section compatible with operating stresses; for compressive loads, buckling has to be avoided without enlarging the thermal cross-section;
-
(2)
using structural materials with a low ratio of thermal conductivity to strength.
