    • 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.
    • 公开了用于节省能量的方法和系统,同时不使用超导磁体系统并且减少重新建立系统的操作条件所需的时间。 传统上,在不活动的时间间隔内,在操作条件下,磁体线圈的温度不允许上升,并且系统保持接通。 这导致浪费大量的能量以将磁体线圈保持在低温。 关闭系统从未是一个选择,因为重新建立操作条件非常耗时且昂贵。 本公开提供了允许系统在高于磁体线圈预期工作温度的温度下空转的方法和系统,这导致明显的节省。

    • Methods and apparatus for cooling systems for cryogenic power conversion electronics are provided. The invention includes systems having electronic power conversion apparatus comprising at least one cryogenically operated semiconductor switch and at least one cryogenically operated capacitor and cooling means for cryogenically cooling the at least one cryogenically operated semiconductor switch and the at least one cryogenically operated capacitor to a temperature between 90 K to 236 K. The systems can also include input/output means for supplying power to said power conversion apparatus and receiving power from said power conversion apparatus. In alternative embodiments, liquid cryogens can be used in heat exchange systems in conjunction with refrigeration cold heads or heat pipes. In these embodiments, the cryogen can be recondensed if boiled.
