Experimental determination of electrical characteristics and circuit models of superconducting dipole magnets

Due to the effects of eddy currents and parasitic capacitance, the electrical characteristics of superconducting magnets are not completely inductive; instead, they are frequency dependent functions. This paper develops a method of accurately measuring the ac characteristics and determining the circuit models of superconducting magnets that characterize the eddy currents and the parasitic capacitance. This measurement method can be used to analyze eddy currents and the resulting circuit model can be used to study the transmission line effect of long magnet strings.<
