Prediction of E-J characteristics in Bi-2223/Ag tapes at low temperature and high magnetic field

Using limited data measurements, the electric field vs. current density (E-J) characteristics of practical Bi-2223/Ag tapes were predicted in a low-temperature and high-magnetic field. This method is based on findings shown in our papers, which describe E-J characteristics according to the percolation model, as a function of temperature, magnetic field and angle of the magnetic field. This method can also estimate critical current density and n-value, given any electric field criterion.
