Strain induced irreversible critical current degradation in highly dense Bi - 2212 round wire
The strain induced critical current degradation of overpressure processed straight Bi-2212/Ag wires has been studied at 77 K in self-field. For the first time superconducting properties, lattice distortions, composite wire stress and strain have been measured simultaneously in a high energy synchrotron beamline. A permanent Ic degradation of 5% occurs when the wire strain exceeds 0.60%. At a wi...
متن کاملMagnetic properties of magnetically textured Bi-2212 ceramics
Abstract: This paper aims at reporting magnetic properties of bulk polycrystalline Bi2Sr2Ca0.8Dy0.2Cu2O8-y samples textured under a magnetic field. The micro structure of these materials is highly anisotropic and exhibits particular features needed to be taken into account in order to interpret their magnetic and electrical properties. First the AC magnetic susceptibility χ = χ' jχ" has been me...
متن کاملFirst Order Transitionof Thevortex Lattice in Disordered Bi-2212 Crystals
Using differential magneto-optical imaging, we address the question of mesoscopic inhomogeneity in underdoped Bi2Sr2CaCu2O8 (Bi-2212) single crystals. Among other features, it is shown that an anomalous temperature dependence of the penetration field and of the first order transition (FOT) field of the vortex lattice in such crystals can be understood as arising from inhomogeneity. The effect o...
متن کاملNonlinear Vibration Analysis of the Composite Cable using Perturbation Method and the Green-Lagrangian Nonlinear Strain
In this study, nonlinear vibration of a composite cable is investigated by considering nonlinear stress-strain relations. The composite cable is composed of an aluminum wire as reinforcement and a rubber coating as matrix. The nonlinear governing equations of motion are derived about to an initial curve and based on the fundamentals of continuum mechanics and the nonlinear Green-Lagrangian stra...
متن کاملEnhancement of Multi-machine Power System Transient Stability Using Superconducting Fault Current Limiters with YBCO and Bi-2212
One of the worst types of fault that a power system should be designed to withstand is a short circuit. Within the various types of fault current limiters, the superconducting fault current limiter (SFCL) has an extremely fast current limitation. The rapid switching action and the self-sensing nature of the superconductor make SFCLs particularly attractive in fault protection. This very fast ti...
