Abstract

A cooldown acceleration loop used to quickly cool down sealed magnetic resonance (MR) magnets. The cooldown acceleration loop is independent of the main cooling system inside the sealed magnet. In particular, a superconducting magnet system includes: a vacuum vessel; one or more shield coils; one or more one or more superconducting main coils, wherein the one or more shield coils and the one or more superconducting main coils are disposed within the vacuum vessel; a hermetically sealed cooling system disposed within the vacuum vessel and containing helium, the one or more shield coils and the one or more superconducting main coils being in thermal contact with the hermetically sealed cooling system; a cooldown acceleration loop comprising one or more fluid conduits disposed within the vacuum vessel and in thermal contact with at least the one or more shield coils and further comprising an inlet port and an outlet port at an exterior of the vacuum vessel; and a coldhead secured to a vacuum vessel and having its highest-stage cold station thermally connected to the hermetically sealed cooling system.
