In a superconducting magnet arrangement, such as used in a magnetic resonance system, and a power management method therefor, an enhanced economic power mode (EPM) is implemented wherein the compressor operation is controlled by magnet pressure, temperature and time, so as to ensure the readiness of the magnet system for a scanning operation upon exiting the enhanced EPM. A processor implementing the enhanced EPM looks for a signal that indicates that the magnet system is operational and, in the absence of that signal for a predetermined period of time, enters into EPM. Exit from EPM occurs if certain conditions are violated, but then re-entry into EPM is attempted (re-starting EPM), thereby making the magnet system ready for operation again, if and when a patient scan is to be implemented.

Power management for cryogen compressors

An arrangement for cryogenic cooling includes a cryogen tank, a cryogenic recondensing refrigerator arranged to cool a heat exchanger that is exposed to the interior of the cryogen tank, and an arrangement for conducting heat from a cooled article to the cryogen tank. A further cryogen tank is provided below the heat exchanger and arranged to receive cryogen liquid recondensed on the heat exchanger.
