Abstract:
A hyperpolarizer for producing polarized noble gases, comprising:an optical pumping cell having a non-polarized gas inlet port and a polarized gas outlet port; a magnetic field source operably associated with said optical pumping cell, said magnetic field source configured to provide a region of homogeneity; a NMR rf coil having first and second opposing ends, said first end positioned adjacent said optical pumping cell within said region of homogeneity; a cryogenic accumulator in fluid communication with said optical pumping cell outlet port; a polarized gas dispensing outlet in fluid communication with said cryogenic accumulator; a polarized gas exit flow line extending between said cryogenic accumulator and said polarized gas dispensing outlet; and a secondary reservoir positioned adjacent said NMR rf coil second end in fluid communication with said polarized gas exit flow path; wherein said NMR rf coil is configured and arranged between said optical cell and said secondary reservoir such that a quantity of gas positioned in either the optical cell or the secondary reservoir can be excited with said NMR rf coil.
