Abstract
A circuit is provided comprising a plurality of series connected superconductive coils. Each of a plurality of series connected shunt resistors is connected in parallel with at least one corresponding series connected superconductive coil. A superconductive switch, which includes a length of superconductive wire, is connected in parallel with the series connected superconductive coils. The switch further includes a first and second heater means which are thermally coupled to the superconductive wire. The first heater means is connectable to an external power supply. The second heater means has a plurality of different sections with each of the shunt resistors connected in parallel to one of the sections so that a quench in any of the superconductive coils causes a section of the second heater means to warm and drive the superconductive switch normal.
