Calculating the Response of a High-Temperture Superconductor to Microsecond Current Pulses with Allowance for Heating

Abstract

Monte Carlo (MC) calculations are made for a two-dimensional model of a layered HTS. The strength of the electric field is calculated for samples subjected to rectangular pulses of current with amplitudes exceeding the critical value. The model considers the heating of the sample caused by the flow of current. Calculations are made for different strengths of magnetic fields and amplitudes of pulse currents. The effect an external magnetic field has on the shape of the response of a superconductor to a rectangular current pulse is determined.
