摘要： A vibration cancellation system for a magnetic resonance imager superconducting C-shaped magnet includes a vibration sensor at a remote end of the separated pole pieces to provide a vibration signal which is phase inverted and converted to an opposing force by a magnetoresistive actuator connected across the support member between the opposite ends of the pole pieces to cancel vibrations which would otherwise adversely affect the homogeneity of the magnetic field in the imaging region of the magnet.

摘要： A method and system for providing a ridethrough reserve for a pulse tube refrigerator (PTR) (12) includes a pressurized tank (42) containing a fluid used to provide fluid pressure and auxiliary power to a PTR (12) during an electrical power supply failure. A pressure regulation valve (pressure valve) (44) releases the fluid from the pressurized tank (42) into the PTR (12). A power regulation valve (power valve) releases from the pressurized tank (12) a driving gas volume for driving a pneumatic motor (46). The pneumatic motor (46) in turn drives a rotary valve (22) of the PTR (12). A release valve (50) releases fluid from the PTR (12) so as to lower the fluid pressure to a predetermined pressure range and enable fluid oscillation in the PTR (12).

摘要： A magnetic shield for a superconducting joint in a superconducting magnet coil includes a superconducting tubular shield of superconducting materials surrounding the joint. The shield extends on either side of the joint a distance equal to the inside diameter of the shield. The coil is wound with niobium titanium conductors. The superconducting shield produces a field anomaly that influences the homogeneity of the imaging volume and an acceptable disturbance in the imaging volume while at the same time providing an ambient field condition that allows the superconducting joint to have a sufficiently low resistance to minimize superconducting current capacity degradation.

摘要： An indium gasket having a configuration which allows the indium to reach its yield point at a relatively low contact pressure. The indium gasket is provided with a multiplicity of openings which are filled by the deforming indium during compression between the cryocooler and the cryocooler interface sleeve of a superconducting magnet system. The creation of openings in the gasket has the effect of decreasing the mechanical interface pressure at which the indium yields. The indium flows at a mechanical interface pressure that does not exceed the structural strength requirements of the cryocooler. The indium flows into the empty spaces formed by the openings, thereby providing the necessary thermal conductance between the cryocooler and the interface sleeve. The result is a relatively small temperature difference between the interface sleeve and the cryocooler during cooling of the superconducting magnets.

摘要： A mixed phase pump for rapidly rotating cryogenic machinery is disclosed, preferably for installation to a superconducting generator rotor. The superconducting generator rotor includes an inner and outer rotor structure joined in a thermally insulated configuration not unlike that of a Dewar flask. The inner rotor contains a support cylinder for a refrigerant, typically helium, which when refrigerated to 3.5.degree. Kelvin at one half a standard atmosphere under the normal rapid rotation of the axially aligned support cylinder, classifies itself into a two-phase liquid gas system. The phases include an outer cylindrical helium pool and an axially inward gaseous core separated by a cylindrical gas-liquid interface. During normal operation of the rapidly revolving rotor, a pump removes the gas for recooling to a liquid state by receiving the gas in the vicinity of the axis of the rotor at an inlet. During abnormal operation including stator short-circuit and rapid rotational vibrational acceleration and deceleration of the rotor, the normal cylindrical interface between the cylindrical helium pool and the vapor core is destroyed. The vapor core in the vicinity of the pump inlet becomes multiphasic and the pump inlet can induct/ingest quantities of liquid. Accordingly, a pump with the liquid gas classification volume located outwardly from the gas inlet to the pump is disclosed. This liquid trap volume in the pump assures that the outward passage of gas only from the pump occurs. Stability of the two-phase gas-liquid system as well as the prevention of thermal stressing of torque-transmitting members of the high speed rotating rotor is prevented.
