Abstract

The wire dynamic simulation has been performed in the superconducting magnet to get the selection standard of structural materials for stable magnet. The equation of motion of each winding was solved with time to simulate the wire motion in a superconducting magnet. The transport current was increased with time, and hence applied force to the wire was changed with time. The minimum quench energy of each winding was calculated and compared with the frictional heating. The quench current was decided when the frictional heating was more than MQE. The material parameters and the winding tension were changed and the wire motion in a superconducting magnet was analyzed.
