Description

An innovative high-field superconducting dipole magnet of Canted-Cosine-Theta (CCT) type has been proposed for Future Circular Collider (FCC) design. The unique mechanical structure intercepts the accumulated forces lowering the stress on the windings. Nevertheless, the former itself also becomes a barrier for heat to quickly propagate in case of a quench. To succeed in the CCT-type magnet design and construction, the quench protection is a challenging part which requires detailed investigation on the electrothermal behavior of this magnet. The potential detection & protection concepts is being studied on both aspects of multiphysics simulations and experiments on the short models that are planned to be built at the Paul Scherrer Institut (PSI). The results will allow us to validate the conceptual design and feasibility of the construction of a fast and efficient quench protection system of CCT-type magnets for accelerators.
