    摘要: A composite sealed vessel is provided. The vessel includes a non-metallic, generally cylindrical inner containment piece, a non-metallic, generally cylindrical outer containment piece disposed around the inner containment piece. A pair of non-metallic flanges are disposed at ends of the inner and outer containment pieces to form a closed structure defining a cavity therein. The vessel also includes a metallic external lining disposed over the closed structure to form a leak-tight pressure boundary.

    摘要: A system and method for protecting a superconductor from a quench condition. A quench protection system is provided to protect the superconductor from damage due to a quench condition. The quench protection system comprises a voltage detector operable to detect voltage across the superconductor. The system also comprises a frequency filter coupled to the voltage detector. The frequency filter is operable to couple voltage signals to a control circuit that are representative of a rise in superconductor voltage caused by a quench condition and to block voltage signals that are not. The system is operable to detect whether a quench condition exists in the superconductor based on the voltage signal received via the frequency filter and to initiate a protective action in response.

    摘要: A correction coil current adjustment circuit for a superconducting magnet to selectively switch various coils in circuit with a power source to provide the desired superconducting current flow and magnetic field homogeneity for magnetic resonance imaging eliminating the need for some of the mechanical leads which extend from the exterior of the magnet to the interior of the cryogen vessel minimizing thermal leak paths and including simplified switching of the various main and correction magnet coils to provide the desired current flow. Inductive coupling from outside the magnet to induce correction coil current flow eliminates additional mechanical leads.
