Abstract: PURPOSE:To prevent bubbles from generating in liquid helium in the vicinity of a superconducting coil by radiation heat by forming a liquid helium vessel in a double wall structure, and providing holes at the gas state section and the liquid state section of the inner tank of the vessel. CONSTITUTION:Since the inner layer 12 of a liquid helium vessel communicates with an outer tank 13 via a liquid state section hole 12 and a gas state section hole 12b, the liquid surface levels of liquid helium 4 are always the same in both tanks. Thus, since there is always the helium 4 on the outer periphery of the layer 12, there is no temperature difference, and no heat is invaded due to radiation. The helium 4 in the tank 13 is evaporated to be vaporized due to the invaded heat radiated from a liquid nitrogen shield 5 to the tank 13 to generate bubbles. The bubbles are passed through the liquid helium in the tank 13, raised to the gas layer, and recovered from a gas helium recovery tube 9b out of the device. Thus, it can prevent the bubbles in the liquid helium in the vicinity of a superconducting coil 2 from generating due to the radiation heat to improve cooling effect.
