| Research Abstract |
The optimization study of the cooling structure has been done in order to establish the design manual of the next generation superconducting magnets. The cryogenic Oscillating Heat Pipes(OHP) have been developed, which is used by being imbedded in the magnet windings as a heat transfer enhancement device. It has been demonstrated for the first time in the world, and the high heat transport properties of the cryogenic OHP have been experimentally confirmed. The obtained data sets have been used to make a fitting by means of multi-regression analysis. The modeling with non-dimensional quantities is useful for the design of cryogenic OHP and the optimization of the cooling structure of the superconducting magnets.
