Can High Current Density HTS Magnets be Quench Protected Using Methods Used to Protect High Current Density LTS Magnets?

High Critical Current Density MgB

High Critical Current Density Superconductivity

This project was focused on a basic scientific problem, one that is at the heart of application and development of superconductivity for efficient energy usage. This is improvement in high current density which can only be achieved by learning to pin vortices to the physical structure of its underlying superconducting material. Quantized vortices are the tornado of electrical supercurrents, ubi...

High Efficiency, High Density, PolyPhase Converters for High Current Applications

As logic systems get larger and more complex, their supply current requirements continue to rise. Systems requiring 100A are fairly common. A high current power supply to meet such requirements usually requires paralleling several power regulators to alleviate the thermal stress on the individual power components. A power supply designer is left with the choice of how to drive these paralleled ...

Quench Analysis of High Current Density Nb3Sn Conductors in Racetrack Coil Configuration

The luminosity upgrade of the Large Hadron Collider (HL-LHC) requires the development of new type of superconducting cables based on advanced Nb3Sn strands. In the framework of the FP7 European project EUCARD the cables foreseen for the HL-LHC project have been tested recently in a simplified racetrack coil configuration, the so-called Short Model Coil (SMC). In 2013 to 2014, two SMCs wound wit...

Direct-drive and Eddy-current Septum Magnets

Two types of thin septum magnets, direct drive and eddy current, were c mainly in 2-D magnetic aspects. For the direct-drive type, the leakage field depend finite permeability of the magnet core and not on the thickness of the septum conduct suggested that the leakage field be controlled by reducing the current in the septum c or by using a correction coil. There were no significant differences...
