Non-cryogenic storage cell for hyperpolarized 129xe

Abstract

A system is disclosed for producing and storing gaseous spin polarized 129 Xe including: a polarizer configured to produce gaseous spin polarized 129 Xe, and a storage apparatus for non-cryogenically storing gaseous spin polarized 129 Xe.

1 . A storage apparatus for non-cryogenically storing gaseous spin polarized by  129 Xe comprising:
 a storage vessel comprising an interior surface substantially surround a storage volume; and   a magnet which produces a substantially uniform magnetic field within the storage volume;   wherein the longitudinal spin relaxation rate of gaseous spin polarized  129 Xe contained in the storage volume due to interactions with the interior surface is about equal to or less than the longitudinal spin relaxation rate of the gaseous spin polarized  129 Xe due to intrinsic mechanisms.
