  • Polarized xenon gas concentration method, polarized xenon gas manufacturing supply device, and MRI system
    Patent number: 8624594
    Abstract: The present invention relates to a polarized xenon gas manufacturing supply device that is provided with a polarization cell 6 that produces a polarized xenon gas by polarizing a mixture of xenon gas and a diluent gas that consists primarily of a high-boiling-point gas that has a boiling point higher than that of the xenon gas, and a condenser (9) that cools the mixed gas discharged from the polarization cell (6) and condenses and separates the high-boiling-point gas by using the difference in boiling points between the xenon gas and the high-boiling-point gas, wherein the supply device is constructed so as to re-vaporize the condensed liquid of the high-boiling-point gas produced by the condenser (9) and introduce it to the polarization cell (6). This polarized xenon gas manufacturing supply device makes it possible to continuously manufacture and supply highly polarized and highly concentrated xenon gas.
