Abstract :
Experiments of quench propagation and stability margin have been performed on a NbTi hollow conductor test module allowing heat conduction only between adjacent layers, while the turns in a layer were thermally insulated. Some of the experimental data on heat propagation and stability margin are reported, and the results of two selected runs are compared with the prediction of a 2-D version of the SARUMAN code. It is shown that the simulation can reproduce the general features of the quench propagation experiments, in one case reaching a quantitative agreement.<>
