Prospects for Improving the Intrinsic and Extrinsic Properties of Magnesium Diboride Superconducting Strands
E. W. Collings, M. D. Sumption, M. Bhatia +2
The magnetic and transport properties of magnesium diboride films represent performance goals yet to be attained by powder-processed bulk samples and conductors. Such performance l…
Increases in the Irreversibility Field and the Upper Critical Field of Bulk MgB2 by ZrB2 Addition
M. Bhatia, M. D. Sumption, E. W. Collings +1
In a study of the influence of ZrB2 additions on the irreversibility field, Birr and the upper critical field Bc2, bulk samples with 7.5 at. % ZrB2 additions were made by a powder…
Solenoidal Coils Made from Monofilamentary and Multifilamentary MgB2 strands
M. D. Sumption, M. Bhatia, F. Buta +7
Three solenoids have been wound and with MgB2 strand and tested for transport properties. One of the coils was wound with Cu-sheathed monofilamentary strand and the other two with…
MgB2/Cu Racetrack Coil: Winding and Transport Testing
M. D. Sumption, M. Bhatia, M. Rindfleisch +3
A racetrack coil using MgB2/Cu strand has been fabricated and tested for transport current density at 4.2 K in self field. The monofilamentary strand was 1.0 mm OD and insulated wi…
Irreversibility Field and Flux Pinning in MgB2 with and Without SiC Additions
M. D. Sumption, M. Bhatia, E. W. Collings +4
Critical current density was measured at 4.2 K for MgB2 strands with and without SiC additions. In some cases measurements were performed on longer (1 m) samples wound on barrels,…
Transport and magnetic Jc of MgB2 strands and small helical coils
M. D. Sumption, M. Bhatia, M. Rindfleisch +2
The critical current densities of MgB2 monofilamentary strands with and without SiC additions were measured at 4.2 K. Additionally, magnetic Jc at B = 1 T was measured from 4.2 K t…
