Abstract

A numerical code (1D+2D) has been developed to simulate quenching in conduction cooled superconducting magnet. The code is formed based on the numerical thermal-physical model to describe an initial hotspot evolution in a practical superconduting coil. The code is in an integrated frame that couples a 1D model and a 2D model, describing the normal zone propagations along the superconductor and among winding turns respectively. Material characteristics of the magnet winding constituents are involved as the basic data to simulate normal zone propagation process. Information such as maximum temperature rise and voltage evolution can be output as the result of code execution. This code is used to perform a quench simulation on the Alpha Magnetic Spectrometer (AMS) superconducting magnet and the simulation results are presented in this paper.
