  • Publication number: 20240136097
    Abstract: A superconducting magnet assembly is provided. The magnet assembly includes a magnet and a switch assembly coupled to the magnet. The switch assembly includes a thermosyphon tube configured to carry cryogen therethrough, a switch, a first pressure valve, and a second pressure valve. The switch is configured to switch between a resistive mode and a superconducting mode, wherein the switch is in thermal contact with the thermosyphon tube. The first pressure valve and the second pressure valve are positioned on the thermosyphon tube and configured to control flow of the cryogen in the thermosyphon tube, and the switch is positioned between the first pressure valve and the second pressure valve. The magnet is configured to generate a polarizing magnetic field based on switching of the switch between the resistive mode and the superconducting mode.

  • Publication number: 20240136098
    Abstract: A superconducting magnet assembly is provided. The magnet assembly includes a magnet configured to generate a polarizing magnetic field, a thermosyphon tube, a main tank, and a metering tank. The thermosyphon tube is in thermal contact with the magnet, the thermosyphon tube configured to carry cryogen therethrough and cool the magnet via the cryogen. The metering tank contains the cryogen and is coupled with the main tank, and the main tank has an interior volume greater than an interior volume of the metering tank, The thermosyphon tube is coupled with the main tank at a first end of the thermosyphon tube and coupled with the metering tank at a second end of the thermosyphon tube, the second end opposite the first end, and the thermosyphon tube and the metering tank define a path along which the cryogen flows.
