Also at the lab's FSU headquarters, the Applied Superconductivity Center advances the science and technology of superconductivity for both the low temperature niobium-based and the high temperature cuprate or MgB 2-based materials. The ASC pursues the superconductors for magnets for fusion, high energy physics, MRI, and electric power ...
In superconductivity, a type-II superconductor is a superconductor that exhibits an intermediate phase of mixed ordinary and superconducting properties at intermediate temperature and fields above the superconducting phases. It also features the formation of magnetic field vortices with an applied external magnetic field.
Although the idea of making electromagnets with superconducting wire was proposed by Heike Kamerlingh Onnes shortly after he discovered superconductivity in 1911, a practical superconducting electromagnet had to await the discovery of superconducting materials that could support large critical supercurrent densities in high magnetic fields.
David C. Larbalestier is an American scientist who has contributed to research in superconducting materials for magnets and power applications. He is currently a Professor of Mechanical Engineering and a member of the Applied Superconductivity Center at the National High Magnetic Field Laboratory at Florida State University, and serves as the Interim Chair of the new Material Science and ...
A bias voltage V is applied across the junction, shifting the Fermi energies of the two superconductors relative to each other by an energy eV, where e is the electron charge. Quasiparticle states exist for energies greater than Δ from the Fermi energy, where Δ is the superconducting energy gap. Green and blue indicate empty and filled ...
The table below shows some of the parameters of common superconductors.X:Y means material X doped with element Y, T C is the highest reported transition temperature in kelvins and H C is a critical magnetic field in tesla.
Superconducting magnetic energy storage (SMES) systems store energy in the magnetic field created by the flow of direct current in a superconducting coil that has been cryogenically cooled to a temperature below its superconducting critical temperature.
Flux Pinning: Flux Tube diagram. Flux pinning is a phenomenon that occurs when flux vortices in a type-II superconductor are prevented from moving within the bulk of the superconductor, so that the magnetic field lines are "pinned" to those locations. [1]
