Abstract :
The quench behavior of a pancake coil made of a copper-stabilized MgB2 tape is investigated with the aim of collecting fundamental know-how on the quench characteristics, and to provide an experimental benchmark for the validation of numerical models. Comparison between numerical and experiment results are reported. Relevant aspects of the quench mechanism are numerically investigated.
