In Se.C.R.E.T.S. (Segregated Copper Ratio Experiments on Transient Stability), the stability performance under transverse field transient is compared for two Nb3Sn cable-in-conduit conductors which differ only because of the different distribution of the s ...
We report results of an angle-resolved high-resolution photoemission study of strongly overdoped Bi2Sr2CaCu2O8+x single crystals with T-c similar to 60 K. We find a nonzero superconducting (SC) gap along all three high symmetry directions in the Brillouin ...
The E-J power law as electric characterization of the HTS material in Finite Element computations has shown good agreement with measurements of field-dependent crtical current density and losses due to transport current. We use this technique to investigat ...
Knowledge of the hydraulic boundary conditions is a prerequisite for accurate estimates of the quench characteristics of superconducting magnets. A set of routines (Flower) has been designed and interfaced to the code Gandalf to provide a simplified model ...
Ag-sheathed (Bi,Pb)2Sr2Ca2Cu3O10 tapes have been developed with a special filament configuration that can be of great interest when a magnetic field is applied to the tape at a significant angle with respect to the a–b planes of the superconductor. The fab ...
Superconducting power cables are one of the most promising energy applications of high-temperature superconductors, Losses in superconducting power cables are mainly due to AC, thermal and dielectric effects. The interplay of cable geometry, operating cond ...
A silicon-based temperature stabilized axial Hall probe with an absolute accuracy of +/-40 ppm in the full range between 0 and 6 T is presented. The absolute calibration of the probe is performed against a nuclear magnetic resonance (NMR) probe. The applic ...
We summarize some of the main results on photoemission spectroscopy in the field of high T-c superconductivity, beginning with a discussion of several open questions. We then briefly analyze our experiments that illustrate the role of doping and of intenti ...
Disorder has a strong influence on the spectral properties of the Bi2Sr2CaCu2O8+x high-T-c superconductor, both in the normal and in the superconducting state. High-resolution photoemission reveals a progressive quasiparticle suppression with increasing di ...
