摘要：
A top loading He-3 cryostat has been developed for scientific experiments with a 60 T pulsed magnetic field facility at Wuhan National High Magnetic Field Center. The cryostat consists of a He-4 bath cryostat, a He-3 insert and a closed circulation system for He-3 gas handling. To eliminate the eddy current heating during the pulse, the tail of the He-3 insert with a vacuum space at the bottom is made from fiberglass tubing coated with epoxy. The He-3 bath is separated from the He-4 bath with the vacuum space. The He-4 bath cryostat provides cooling power to condense He-3 gas by a neck tube on top of the tail. Experimental results have shown that the sample can be cooled down to 385 mK and kept cold for more than 150 second by one-shot cooling, which is sufficiently long for an experiment in a pulsed high magnetic field.
