Bond graphs are widely used in the modelling of various systems. In this work, we are exploring the idea of using bond graphs to model the event of 'Quench' in a superconducting magnet. Quench is the event where a portion of the magnet turns normal, i.e. resistive. This starts Joule heating at that spot, and the stored energy of the magnet will be deposited at that point. This can lead to temperature rise and high voltage arcs. Here a bond graph model is proposed to study the electrical and thermal domain of the quench event. The model is further used to simulate the quench in a 6T superconducting solenoid magnet, and the results are compared with the results of a commercial quench solver. The results show close agreement with minor variations due to various assumptions taken in both cases. With the case successfully demonstrated, the model can be improved further to simulate more complex magnet systems and can provide a robust and fast method for quench simulation.
