Low field MgB 2 and NbTi fast ramped coils: temperature behaviors and empirical comparison
As it is well known, all types of superconductors are affected by AC losses Those losses occur when a time varying current flows in a superconductor or when it is subjected to a variable magnetic field. The main effect of these losses on the conductor is a temperature rise due to the energy dissipation within the superconductor The main task of superconductor manufacturers is to optimize the design of the wire in order to reduce AC losses according to the magnet requirements.
Many methods were previously studied in order to reduce the magnitude of this loss. This poster presents the results of an empiric experiment designed to demonstrate the theoretical benefit of MgB 2 with respect to standard NbTi, in low field/fast ramped applications.
