| 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' intended operating temperature, which results in noticeable savings. | ||||||
