Magnetic holding field for cryogenically accumulated polarized 129Xenon

摘要

An apparatus and a method for providing a magnetic holding field about a chamber for accumulating frozen <129>Xe. The apparatus includes a magnetic field source and a yoke for supporting the magnetic field source about the chamber. The magnetic field source provides a magnetic holding field having a field strength of greater than 2 kiloGauss. The apparatus may further include yoke for coupling the magnetic holding field through a portion of the chamber.
