Description
One of the aspects studied during the design of the 16 T Nb3Sn dipole magnets was their safety during quenches occurring in magnet operation and testing. To ensure that the foreseen quench protection technologies can limit the magnet temperatures and voltages to safe values, several criteria related to quench protection were included in the magnet design. As the magnet designs matured, detailed protection schemes including quench heaters and/or CLIQ (Coupling Loss Induced Quench) were developed. In this presentation, we show the final proposed protection schemes with CLIQ, which is the baseline option, and the protection schemes using quench heaters, which can provide a back-up solution in case future experiments will show some unexpected behaviour related to the novel CLIQ technology. We consider the Cosθ, Block, and Common-coil magnets developed within the EuroCirCol collaboration.
