15. Processing of bulk Bi-2223 high-temperature superconductor
The Bi2Sr2Ca2Cu3 O10+x (Bi-2223) is one of the main high temperature superconductors for applications. One of these applications is the Superconductor Fault Current Limiter (SCFCL), which is a very promising high temperature superconducting device. SCFCL's can be improved by using bulk superconductors with high critical currents, which requires a sufficientl

16. Low frequency fields driven by the Ergodic Magnetic Limiter at rational surfaces in rotating tokamak plasmas
The rotating low frequency (RLF) field penetration and dissipation and the effect of ponderomotive forces driven by Ergodic Magnetic Limiter (EML) on the poloidal/ toroidal flow in tokamak plasmas are discussed. EML coils are represented as a sheet current expanded in Fourier series with poloidal/toroidal wave numbers M/N depending on coil shape and feeding.

17. ESTUDO DA FUSÃO E SOLIDIFICAÇÃO DA FASE BI-2212 E SEUS MECANISMOS DE SUPERCONDUÇÃO / STUDY OF BI-2212 PHASE MELTING AND SOLIDIFICATION AND ITS SUPERCONDUCTING MECHANISMS
High temperature superconductivity was discovered in 1986. Since then more than 150 new superconductors (cuprates, bismuthates, borides and fullerite) with critical temperature higher then 23,3K (the highest critical temperature for low temperature superconductors) have been synthesized. Many of them rise interest from the scientific viewpoint and are suitab

18. Development of Bulk Bi2+xSr3-yCa yCu 2O8+delta Superconductors by Partial-Melting Route for Fault Current Limiters Application
The production of bulk Bi2+xSr3-yCa yCu 2O8+delta (Bi-2212) superconductors for fault current limiter application was developed via a partial-melting route. Aiming high Ic (critical current), which is the essential superconducting characteristic for application of this material in the construction of Fault Current Limiters (FCL), the produced blocks have pre
