Abstract
A cryogenic magnet structure includes at least two superconducting coils that are substantially symmetric about a central axis and on opposite sides of a median plane. At least one cryostat contains the superconducting coils; and a magnetic yoke surrounds the superconducting coils and contains at least a portion of a chamber, wherein the median plane extends through the chamber. At least one integral maintenance boot assembly is in thermal contact with the superconducting coils and is configured to preserve a sealed vacuum in the cryostat; and a cryogenic refrigerator is in thermal contact with the maintenance boot assembly and is configured to cool the superconducting coils below their critical superconducting temperatures and is configured for removal from thermal contact with the integral maintenance boot assembly without breaking the sealed vacuum in the cryostat.
