ABSTRACT:
A superconductive-magnet electrical circuit for protecting a superconductive magnet from damage during a quench in the superconductive magnet coil assemblage. A first circuit portion detects the quench. A pilot superconductive switch has its superconductive wire portion superconductively coupled in series with the coil assemblage and has its resistive heater portion, which is activated by the first circuit portion, located near the superconductive wire portion. A second circuit portion (such as a resistive heater or an energy dump resistor) quench protects the coil assemblage and is triggered by the superconductive wire portion switching from the superconductive to the resistive mode.
