Patent number: 7325293Abstract: A multi-filament superconducting wire in which the filaments comprise zirconia-stabilized ultra-fine grain Nb3Sn. The superconducting wire is formed by wire-drawing a preform comprising a metallic matrix and at least one niobium alloy rod having zirconium and oxygen in solid solution and heat treating the drawn wire in the presence of tin to yield at least one continuous filament comprising ultra-fine grain Nb3Sn having semi-coherent ZrO2 precipitates disposed therein. The ZrO2 precipitates serve to stabilize the ultra-fine grain microstructure of the Nb3Sn at temperatures up to 1100° C. and allows Nb3Sn to maintain the ultra-fine grain microstructure when heat treated at temperatures that are greater than those previously used. By using higher temperatures to form Nb3Sn, the time required for heat treatment can be significantly reduced.Type: GrantFiled: April 19, 2006Date of Patent: February 5, 2008Assignee: General Electric CompanyInventors: Mark Gilbert Benz, Theodore McCall Evenden, Judson Sloan Marte, Thomas Robert Raber

At least one gradient coil is positioned between an imaging volume and the superconducting coil without any thermal shielding interposed between the gradient coil and the superconducting coil. A method of forming an MRI system includes forming at least one winding of the main field generating coils with high temperature superconducting material, positioning the winding in a vessel for receiving cryogenic fluid, and positioning a gradient coil between the imaging volume and the winding without placing a thermal radiation shield between the gradient coil and the winding.Type: GrantFiled: November 17, 2005Date of Patent: January 15, 2008Assignee: General Electric CompanyInventors: J.

Patent number: 6584172Abstract: A brazed X-ray target includes a metallic cap and a graphite back including a nonlinear record groove attached thereto along a stepped surface. An upper corner joint of the stepped surface is distanced from a cap outer edge and a focal track where the maximum heat is generated during use of the target. The graphite back is extended outward toward the cap outer edge to increase a thermal storage of the graphite, and a recess is formed into the cap to maintain a selected moment of inertia of the target and thereby maintain the rotordynamics of a given X-ray tube.Type: GrantFiled: August 26, 2002Date of Patent: June 24, 2003Assignee: General Electric CompanyInventors: Thomas C.
