The Optimal Air Gap Between the Pancake Windings in a HTS Magnet Consisting of Insert and Outsert Magnet

In a high temperature superconducting magnet consisting of pancake windings, the perpendicular magnetic field considerably reduces the value of the critical current of the outer pancake windings due to anisotropy. An air gap was inserted between each pancake winding in this paper to reduce the decrement of the critical current in each pancake winding. In a… (More)
