Abstract
Provided is a helium recondensation apparatus for a cryostat, which can stably recondense vapor of helium in the cryostat while preventing a pipeline for the recondensation from being clogged. A recondensation apparatus includes a freezer, a first heat exchanger, a first recondensing chamber, and a first connection part. The first heat exchanger stores heat-exchanging helium in a helium tank included in an NMR apparatus, and permits the heat-exchanging helium to evaporate owing to heat of vaporization taken from vapor of coolant helium in the helium tank, thereby permitting the coolant helium to recondense through heat exchange with the heat-exchanging helium. The first connection part is separated from the coolant helium in the helium tank and permits the heat-exchanging helium to flow between the first heat exchanger and the first recondensing chamber therethrough.
