ABSTRACT:
A helium cooling apparatus includes a liquid helium container which stores liquid helium and a condensation chamber incorporating a condensation heat exchanger for condensing a gas helium into liquid helium. A transfer tube allows the liquid helium container to communicate with the condensation chamber. The transfer tube has a gas flow path and a liquid helium flow path independently thereof. When the liquid helium in the liquid helium container is evaporated into gas helium, the gas helium is guided to the condensation chamber through the gas helium flow path. The gas helium is condensed by a condensation heat exchanger into liquid helium. The liquid helium is guided to the liquid helium container through the liquid helium flow path.
