Transient Stability Analysis of the SeCRETS Experiment in SULTAN

We present here the results of the analysis of the stability experiment SeCRETS, performed on two Nb$_{3}$Sn cable-in-conduit conductors with the same amount of total copper stabilizer, but different degree of segregation. The model used for the analysis, including superconducting strands, conductor...

description We present here the results of the analysis of the stability experiment SeCRETS, performed on two Nb$_{3}$Sn cable-in-conduit conductors with the same amount of total copper stabilizer, but different degree of segregation. The model used for the analysis, including superconducting strands, conductor jacket and helium, is solved with the code GandalfTM. We obtain a qualitative agreement of simulation results and experimental values. The simulation results confirm that in the operation regime explored in the experiment the segregated copper is not effective for stability. The details of the current sharing and the approximation taken for the transient heat transfer are shown to be critical for the interpretation.
