Numerical and Experimental Study for the Quench Propagation of A Test Superconducting Magnet

Quench protection design is the key task of the manufacture of a superconducting magnet. The analysis of quench propagation of the superconducting coils is very important for the quench protection design. A numerical model based on the control volume method has been built to simulate the quench propagation. An experiment with five test superconducting coils and an ambient coil was performed to verify the numerical code. The quench protection method of using the heater is proved effective on accelerating the quench propagation by both the simulation and the experiment. (C) 2013 Published by Elsevier B.V.
