Superconducting magnetic energy storage
A Superconducting Magnetic Energy Storage (SMES) system stores energy in a superconducting coil in the form of a magnetic field. The magnetic field is created with the flow of a direct current (DC) through the coil. To maintain the system charged, the coil must be cooled adequately (to a “cryogenic” temperature) so as to manifest its superconducting properties – no resistance to the flow of cur...
متن کاملEvidence for two energy scales in the superconducting state of optimally doped (Bi,Pb)2(Sr,La)2CuO6+delta.
We use angle-resolved photoemission spectroscopy to investigate the energy gap(s) in (Bi,Pb)2(Sr,La)2CuO6+delta. We find that the spectral gap has two components in the superconducting state: a superconducting gap and pseudogap. Differences in their momentum and temperature dependence suggest that they represent two separate energy scales. Spectra near the node reveal a sharp peak with a small ...
متن کاملSuperconducting Magnetic Energy Storage: Status and Perspective
The SMES (Superconducting Magnetic Energy Storage) is one of the very few direct electric energy storage systems. Its energy density is limited by mechanical considerations to a rather low value on the order of ten kJ/kg, but its power density can be extremely high. This makes SMES particularly interesting for high-power and short-time applications (pulse power sources). A SMES releases its ene...
متن کاملMagnetic Energy and Electron Inertia in a Superconducting Sphere
The hypothesis that the magnetic energy of a current circuit is the kinetic energy of the effective conduction electrons, developed in a previous Monograph, is applied to the case of a conducting sphere without resistivity in a uniform magnetic field. A surface current is induced which prevents the growth of a magnetic field within the sphere, and expressions are found for the number and veloci...
