Quench Protection of Curved Solenoids for High Intensity Muon Beamlines

A quench protection system for superconducting curved segmented solenoids has been experimentally studied. The curved solenoids consist of short straight solenoids aligned along a curved beamline axis. The quench propagation between the short solenoids may not naturally occur because of the separation between the solenoids, and an artificial quench need to be induced by a protection heater for each short solenoid to boost the quench propagation. A protection heater driven by the coil self current was tested with a model coil.
