Abstract
In one aspect of the present invention a superconductive magnet for use in a magnetic resonance imaging and spectroscopy is provided. The magnet comprises a cylindrical coil form having a plurality of superconductive coils situated coaxially on the cylinder, spaced apart from one another. A plurality of pairs of thermal bridges each comprising a bar shaped section connecting a first and second end portion is also provided. The first end section has a greater surface are than the second end section. Each of the pairs of thermal bridges is situated between a respective pair of adjacent coils. The bar section of each of the thermal bridges extends axially between the adjacent coils. In each pair, the first end of one of the pair and the second end of the other of the pair are in thermal contact with one of the adjacent coils, the second end of one of the pair and the first end of the other of the pair are in thermal contact with the other coil of the adjacent pair. Each of the thermal bridges act as a heat flux amplifier in an opposite direction between the adjacent coils due to different end portion areas in contact with the adjacent coils.
