Patent ID: 8217293

Claim:
A method for producing nuclear spin polarized xenon gas, comprising: coupling piping to a sealed glass cell, filled with solid material consisting of solid rubidium and solid xenon, during which the sealed glass cell becomes unsealed, wherein said sealed glass cell is in a pressure reducing state of being absent of oxygen; heating the glass cell filled with solid rubidium and solid xenon in the pressure reducing state of being absent in oxygen to produce therein gaseous xenon and a mixture of gas and liquid phases of rubidium; irradiating with a laser beam the gaseous xenon and the mixed-phase rubidium that is in the glass cell and is produced from the solid xenon and solid rubidium, and applying a magnetic field to the irradiated gaseous xenon and mixed-phase rubidium in the glass cell to achieve the nuclear spin polarized xenon gas, wherein nuclear spin polarized xenon gas is achieved at a concentration of at least 80% by said heating, irradiating and applying without a need for subsequent freezing to achieve said concentration.
