Abstract
A method and apparatus for the accumulation of hyperpolarized 129Xe is described. A gas mixture comprising 129Xe is flowed through a heat exchanger tube from the first end to the second end. Concurrently, the outer surface of the heat exchanger tube is controllably refrigerated, beginning with the second end, to a temperature low enough to freeze the 129Xe on the inner surface of the heat exchanger tube.
