Simultaneous Constraint And Phase Conversion Processing Of Oxide Superconductors

View page
US Patent:
6555503, Apr 29, 2003
Filed:
Sep 20, 2000
Appl. No.:
09/665882
Inventors:
Qi Li - Marlborough MA
Elliott D. Thompson - Coventry RI
Eric E. Hellstrom - Madison WI
David C. Larbalestier - Madison WI
Kenneth L. DeMoranville - Jefferson MA
Jeffrey A. Parrell - Roselle Park NJ
Jodi L. Reeves - Madison WI
Assignee:
American Superconductor Corporation - Westborough MA
International Classification:
H01B 1200
US Classification:
505432, 505433, 505501, 505822
Abstract:
A method of making an oxide superconductor article includes subjecting an oxide superconductor precursor to a texturing operation to orient grains of the oxide superconductor precursor to obtain a highly textured precursor; and converting the textured oxide superconducting precursor into an oxide superconductor, while simultaneously applying a force to the precursor which at least matches the expansion force experienced by the precursor during phase conversion to the oxide superconductor. The density and the degree of texture of the oxide superconductor precursor are retained during phase conversion. The constraining force may be applied isostatically.

Mechanical Decoupling In High-Temperature Superconducting Tapes

View page
US Patent:
8530390, Sep 10, 2013
Filed:
Dec 6, 2011
Appl. No.:
13/312454
Inventors:
David K. Hilton - Tallahassee FL, US
Matthieu Dalban-Canassy - Tallahassee FL, US
Hubertus W. Weijers - Crawfordville FL, US
Ulf P. Trociewitz - Crawfordville FL, US
David C. Larbalestier - Tallahassee FL, US
Assignee:
Florida State University Research Foundation - Tallahassee FL
International Classification:
H01L 39/24
US Classification:
505434
Abstract:
A novel method and structure for creating a high-temperature superconducting tape. The concept of the invention is to use a conductor insulation which not only electrically insulates the conductors of the coil windings from each other, but also mechanically insulates them from the much stronger encapsulant. The insulation material mechanically decouples the conductor from the encapsulant at the boundary between them, thereby preventing damage as a result of thermal and electromagnetic shearing forces. The proposed structure allows the encapsulant to continue performing its functions of preventing coarse motion and stabilizing the coil as a whole, while allowing fine relative displacements of individual coil windings caused by radial stress gradients.

Niobium-Titanium Superconductors Produced By Powder Metallurgy Having Artificial Flux Pinning Centers

View page
US Patent:
52269477, Jul 13, 1993
Filed:
Feb 17, 1992
Appl. No.:
7/837038
Inventors:
Paul D. Jablonski - Madison WI
David C. Larbalestier - Madison WI
Assignee:
Wisconsin Alumni Research Foundation - Madison WI
International Classification:
C22C 1400
US Classification:
75245
Abstract:
Superconductors formed by powder metallurgy have a matrix of niobium-titanium alloy with discrete pinning centers distributed therein which are formed of a compatible metal. The artificial pinning centers in the Nb-Ti matrix are reduced in size by processing steps to sizes on the order of the coherence length, typically in the range of 1 to 10 nm. To produce the superconductor, powders of body centered cubic Nb-Ti alloy and the second phase flux pinning material, such as Nb, are mixed in the desired percentages. The mixture is then isostatically pressed, sintered at a selected temperature and selected time to produce a cohesive structure having desired characteristics without undue chemical reaction, the sintered billet is reduced in size by deformation, such as by swaging, the swaged sample receives heat treatment and recrystallization and additional swaging, if necessary, and is then sheathed in a normal conducting sheath, and the sheathed material is drawn into a wire. The resulting superconducting wire has second phase flux pinning centers distributed therein which provide enhanced J. sub. ct due to the flux pinning effects.

Wrapped Tantalum Diffusion Barrier

Appl. No.:
5/933302
Inventors:
Morris S. Young - Murray Hill NJ
David C. Larbalestier - Madison WI
Assignee:
Airco, Inc. - Montvale NJ
International Classification:
B21C 3712
H01L 3906
US Classification:
428614
Abstract:
A multifilamentary stabilized superconductor of the A-15 type is disclosed wherein the A-15 compound is formed on rods of niobium or vanadium by diffusion of tin or gallium, respectively, from a copper alloy matrix and wherein stabilization is provided by an external layer of copper. The stabilizing copper is protected from tin or gallium diffusion by a number of spirally wrapped layers of tantalum separated from one another by copper layers.

Magnetometer For Large Magnetic Moments With Strong Magnetic Anisotropy

View page
US Patent:
20220381854, Dec 1, 2022
Filed:
May 26, 2022
Appl. No.:
17/804297
Inventors:
- Tallahassee FL, US
George Miller - Tallahassee FL, US
David Larbalestier - Tallahassee FL, US
International Classification:
G01R 33/09
H01L 43/10
H01L 43/02
Abstract:
This disclosure presents systems, devices, and methods that use magnetometers to measure large magnetic moments with strong magnetic anisotropy. A torque magnetometer may include an actuator driven by a motor, a load cell coupled to the actuator, a rotatable spool having a platform configured to hold a sample of a superconductor material, where the rotatable spool is coupled to the load cell by a first line, a pulley, and a second line extending between the rotatable spool and a counterweight, where the second line is positioned on the pulley. Movement of the actuator may cause the rotatable spool to rotate an angle of the platform relative to a magnetic field about the rotatable spool, and the load cell is capable of measuring the tension on the first line.

Inventors:
- Tallahassee FL, US
Youngjae Kim - Tallahassee FL, US
Ulf P. Trociewitz - Crawfordville FL, US
Charles L. English - Saint Marks FL, US

Abstract:
A coil for a magnet includes a superconductor comprising a BiSrCaCuO (Bi-2212) high temperature superconductor (HTS) filament. The HTS filament can be encased in a protective conducting sheath. The superconductor is wound to form a coil. A reinforcement winding is wound with the superconductor. The reinforcement winding can be a wire, a tape, a band, and an outer layer encasing the superconductor filament. A method of making a coil for a magnet, a composite superconductor for a magnet, and a magnet are also disclosed.
