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.

A valve for controlling cryogen egress from a cryogen vessel has a housing having a low pressure side and a high pressure side with a fluid path defined between. A valve element is interposed between the low pressure side and the high pressure side of the housing. A mechanism is provided for holding the valve element against a valve seat. The mechanism has a cam shaft that is rotatable to displace the valve element from its seat to open the fluid path.

Multi-purpose valve for cryogen gas egress

A burst disc arrangement for a cryostat comprising a replaceable burst disc () held in compression between a high-pressure flange formed at an end of a high-pressure conduit (), and a low-pressure flange () formed at an end of a low-pressure conduit (). In particular, the burst disc arrangement further comprises: a housing () enclosing the high- and low-pressure flanges; and compression means (), distributed around the housing () and being arranged to bear upon the one of the flanges (), so as to urge it towards the other flange, thereby retaining the burst disc () in compression between the flanges. The housing () includes a first opening () large enough to allow the replaceable burst disc () to pass therethrough.
