Abstract:A 2D quench propagation finite element model in COMSOL, based on earlier work by Volpini, was developed and results were compared to literature. The model was used to calculate the quench propagation velocity and minimum quench energy for aluminum stabilized NbTi superconducting cables for different current levels and RRR values for the stabilizer. Both single cable and coil simulations were performed to simulate the ECT and BT conductors used in the ATLAS B00 test coil. Quench propagation velocity results agreed well with measurement values found in literature. Minimum quench energy results were within 50% compared to measurement values found in literature for the BT conductor simulations. For the ECT conductor simulations this was only the case at high currents.
