Development of 4.0 μm thick film REBCO tapes with length over 10 m by Ohmic heating technique

Autor: Eduard Galstyan, Venkat Selvamanickam, Kalyan Boyina, Goran Majkic, Mahesh Paidpilli

Publikováno v: MRS Advances. 6:718-722

High-temperature superconducting REBCO (RE-(Gd,Y)Ba2Cu3O7-δ)-coated conductor has an immense potential to enable magnetic fields above 20 T because of its high current-carrying capacity, high irreversibility field, and good mechanical properties. Ad

Development of RE-Ba-Cu-O superconductors in the U.S. for ultra-high field magnets

Autor: Mahesh Paidpilli, Venkat Selvamanickam

Publikováno v: Superconductor Science and Technology. 35:043001

High-temperature superconductors (HTSs) make it possible to achieve magnetic fields beyond the 23.5 T limit of low-temperature superconductors. For higher energy density, high-performance HTS with J e > 1000 A mm−2 enables reduction in coil winding
