  • Thermally passive magnet mounting system for an MRI signa profile magnet in mobile trailer van
    Patent number: 5877665
    Abstract: In a mobile magnetic resonance imaging van, the challenge is to design a magnet mounting system such that the top and bottom poles of the magnet are within magnet temperature gradient specifications for good image quality. The present invention provides such a mounting system and method for mounting a permanent magnet in a mobile trailer vehicle. Mounting bolts are used to mount the permanent magnet to the floor of the mobile trailer vehicle. Laminate or composite insulating material, preferably stacked Phenolic pads, thermally insulate the permanent magnet from the trailer floor. A second set of stacked insulating material pads thermally insulate the mounting bolts from the permanent magnet.

  • Superconducting switch thermal interface for a cryogenless superconducting magnet
    Patent number: 5394129
    Abstract: A thermal interface for a superconducting switch of a cryogenless superconducting magnet is thermally insulated from and supported by the main magnet support structure and is connected to the cold stage of a cryocooler by a thermal bus bar having a coefficient of thermal conductivity which decreases as the temperature of the switch increases.
