REDUCED-GAS-FLOW ELECTRICAL LEADS FOR SUPERCONDUCTING MAGNET SYSTEM

摘要

A device is employed for an apparatus including an electrically conductive coil (230) which is disposed within a cryostat (210) and which is configured to produce a magnetic field when an electrical current is passed therethrough. The device dissipates heat from an electrical contact which is disposed within the cryostat and which is configured to supply electrical power to the electrically conductive coil, The device includes: a cooling gas circuit (326) configured to supply a cooling gas to the electrical contact which is disposed within the cryostat and configured to supply electrical power to the electrically conductive coil; and a heat exchanger (308) disposed within the cryostat and configured transfer heat from the electrical contact to the cooling gas to raise the temperature of the cooling gas.
