【 摘 要 】

The MICE coupling coil is fabricated from Nb-Ti, which has high quench propagation velocities within the coil in all directions compared to coils fabricated with other superconductors such as niobium tin. The time for the MICE coupling coil to become fully normal through normal region propagation in the coil is shorter than the time needed for a safe quench (as defined by a hot-spot temperature that is less than 300K). A MICE coupling coil quench was simulated using a code written at theInstitute of Cryogenics and Superconductive Technology (ICST) at the Harbin Institute of Technology (HIT). This code simulates quench back from the mandrel as well as normal region propagation within the coil. The simulations included sub-division of the coil.
