Abstract:
An open architecture recondensing cryogen superconducting magnet system including an upper and lower cryogen vessel each including superconducting magnet coils and a liquid cryogen to provide a magnetic field therebetween, and at least one support and interconnect assembly between the vessels, thermal apparatus to prolong superconducting ride-through operation comprising:a recondenser to recondense cryogen gas back to liquid cryogen connected to at least one of said cryogen vessels;said thermal apparatus including:a first layer of highly thermally conductive material around said upper cryogen vessel;a second layer of highly thermally conductive material around said lower cryogen vessel;said interconnect assembly between said upper and lower vessels including a highly thermally conductive material thermally connecting said first and second layers of highly thermally conductive material;said highly thermally conductive material providing a thermal path for isothermalizing said upper cryogen vessel and said lower cryogen vessel and conducting heat away from the higher temperature cryogen vessel to the lower temperature cryogen vessel to prolong the superconducting ride-through period.
