Ever increasing liquid helium (LHe) price has pushed
researchers to design background magnets that could
operate in conduction cooling mode. High Tc
superconductor e.g. MgB
a promising candidate for conduction cooled magnet. But
high strain sensitivity of MgB
could be a limiting factor in designing a whole body MRI
magnet of 1.5T or higher. In this work, strain
sensitivity of an optimized 1.5T conduction cooled MgB
magnet is numerically studied. The stress and strains
behavior of the design shows viability of building such
conduction cooled magnet.
