【 摘 要 】

The 9.4 T MRI superconducting magnet is being fabricated. A quench simulation code based on anisotropic continuum model has been developed for the quench protection design. The quench behavior of the magnet is studied by means of the code. A commercial software based on finite element method is also applied to the quench simulation of the magnet. The calculation results of the two numerical methods have been compared and analyzed.
