METHOD OF PRODUCING OPTICALLY PUMPED HYPERPOLARIZED GAS

摘要

Methods producing hyperpolarized gas by: (a) heating a target gas in an optical pumping cell (20), the optical pumping cell (20) having opposing top and bottom portions; (b) polarizing the target gas in the optical pumping cell; (c) directing heated polarized gas to flow out of the top portion of the optical pumping cell to a storage reservoir (30), the storage reservoir having a temperature that is less than the temperature of the heated target gas flowing out of the optical pumping chamber; and (d) flowing previously polarized gas from the reservoir (30) into the optical pumping cell (20).
