  • Publication number: 20080242974
    Abstract: A system for polarizing a material to be used in techniques employing magnetic resonance (MR) is provided. The polarizer system includes a cooling chamber having a cryogenic refrigerant therein for use in polarizing a substance. A sorption pump is connected to the cooling chamber to reduce a pressure therein to allow for hyperpolarizing of the sample. The sorption pump is cooled by a refrigeration system to promote molecular adsorption in the sorption pump. The cooling chamber, sorption pump, and refrigeration system are arranged in a closed system.

  • Publication number: 20040244386
    Abstract: A cryogen pressure vessel assembly for a superconducting magnet comprises an inner former, an outer former, and an outer shell. The inner former has a plurality of superconducting magnet coils wound thereon, and the outer former has a plurality of bucking coils wound thereon. The inner former, the outer former, and the outer shell form a fluid boundary for a cryogen. In one aspect, a pressure face is formed on at least one of the coil formers, and a radial slot for receiving wires entering and exiting a coil is disposed in the pressure face. A plurality of wire clamps are positioned in the radial slot, with each wire clamp in the plurality of wire clamps including: a front face extending coplanar with the pressure face, a rear face opposite the front face, the rear face contacting a back surface of the radial slot, and a recess formed in the rear face, the recess forming a channel for passage of the wires.
