Investigation on effects of conductor concepts on 3D quench propagation in superconducting coils using the code system MAGS

  • R. Meyder
Article

Abstract

Quench propagation is analysed for two different conductor types, foreseen for a Tokamak and a Stellarator type fusion machine, respectively. For the analysis the code system MAGS is used. In the paper MAGS is presented briefly. The analysis considers quench in a small layer wound coil with separate coolant flow in the two layers modelled. Quench is initiated in the first layer and propagates in this coolant channel as well as to the second coolant channel, via heat conduction. Due to the different design, very different front velocities and peak pressures were determined.
