Description
A top loading 3He 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 4He bath cryostat, a 3He insert and a closed circulation system for 3He gas handling. To eliminate the eddy current heating during the pulse, the tail of the 3He insert with a death vacuum at the bottom is made from fiberglass tubing coated with epoxy. The 3He bath is separated from the 4He bath with the death vacuum. The 4He bath cryostat provides cooling power to condense 3He gas by a neck tube on top of the tail. Experimental results have shown that the sample temperature can be cooled down to 385 mK and kept for more than 150 second by one-shot cooling, which is sufficiently long for an experiment in a pulsed high magnetic field.
