Abstract
Methods of collecting, thawing, and extending the useful polarized life of frozen polarized gases include heating a portion of the flow path and/or directly liquefying the frozen gas during thawing. A polarized noble gas product with an extended polarized life product is also included. Associated apparatus such as an accumulator and heating jacket for collecting, storing, and transporting polarized noble gases include a secondary flow channel which provides heat to a portion of the collection path during accumulation and during thawing.
Claims5
A method for producing a polarized noble gas product, comprising the steps of:
- polarizing the noble gas to a first polarization level;
- freezing the noble gas from said polarizing step in the presence of an applied magnetic field;
- and
- thawing the noble gas from said freezing step such that the noble gas product resulting from said thawing step exhibits a second polarization level at least 30% of said first polarization level.
