MAGNETIC HOLDING FIELD FOR CRYOGENICALLY ACCUMULATED POLARIZED 129XENON

摘要

An apparatus and a method for providing a magnetic holding field about achamber (80) for accumulating frozen 129Xe. The apparatus includes a magneticfield source (58; 60) and a yoke (40) for supporting the magnetic field source(58; 60) about the chamber (80). The magnetic field source (58; 60) provides amagnetic holding field having a field strength of greater than 2 kiloGauss.The apparatus may further include yoke (40) for coupling the magnetic holdingfield through a portion of the chamber (80).
