Computer Simulations of Quench Properties of Thin, Large Superconducting Solenoid Magnets

Abstract

Measured quench data of a 1 m φ×1 m thin superconducting solenoid magnet with a single layer aluminum-stabilized NbTi/Cu superconductor of 269 turns were fitted by computer simulations using the one-dimensional approximation. Parameters obtained were used to study quench properties of a 3 m φ×5 m (1.5 Tesla) thin superconducting solenoid magnet with a stored magnetic energy of 30×10⁶ J. Conductor dimensions with which the solenoid could be built substantially safe for the full field quench were optimized.
