Quench Modeling of the GaToroid Demonstrator Magnet for Hadron Therapy

Abstract

In the design of superconducting magnets, ensuring thermal stability during operation is of paramount importance. This study aims to predict heat propagation and temperature distribution during a quench event in the Low Temperature Superconductor (LTS) demonstrator of the GaToroid coil. An efficient 1-D Finite Element Method (FEM) quench propagation model was employed, incorporating a thermal network model to account for heat interactions between turns in the transverse direction. The study highlights the relevance of accounting for the transverse propagation for an accurate description of the normal zone propagation. The predicted numerical results are validated against experimental data obtained during a dedicated test campaign.
