摘要：

We have developed a new computer code that addresses quench simulation and analysis of magnetically coupled epoxy-impregnated magnet system. The new computer code contains several new provisions: 1- it includes the effect of AC loss from the field variations in the winding due to field change because of the fast current transfer between the magnetically coupled solenoids; 2-simultaneous solution of the propagation velocities in all directions in each coil by solving the thermal diffusion equation in the three directions (tangential, radial and axial). In addition to the above new features, the code solves for the currents, voltage, temperature distribution, and resistance of each coil as function of time. Thermal simulation of the protection switch and the quenching heaters is part of the new code.
