methods and systems are disclosed for saving energy while a superconducting magnet system is not being used and for reducing the time required for the re - establishment of the operating conditions of the system . traditionally , during an inactive time interval , the temperature of the magnet coils is not allowed to rise , and the system is kept on , in operating conditions . this results in wasting a large amount of energy for keeping the magnet coils at cryogenic temperatures . turning the system off has never been an option since re - establishment of the operating conditions is very time consuming and costly . the present disclosure offers methods and systems that allow idling of a system in temperatures higher than the magnet coils &# 39 ; intended operating temperature , which results in noticeable savings .
