Stability and Fast Heat Removal with He-II Cooling for Pulsed Superconductive Magnets

摘要

The use of pressurized superfluid helium between 1.6 exp 0 K and 1.8 exp 0 K is being considered for a number of superconducting magnet applications. This type of cooling is particularly interesting in the case of pulsed field magnets where large heat fluxes need to be evacuated in a short time. This paper reviews a few recent experiments on heat transport properties and stability in He-II, which contribute to evaluating its potential use for such an application. Present technology is illustrated by the description of a large test facility recently operated at Saclay. (Atomindex citation 11:545965)
