Abstract
A superconductive-magnet electrical circuit includes a superconductive-coil assemblage having a second coil portion coupled in series with and between first and third coil portions with the third coil portion coupled in series with and between the second and a fourth coil portion. A bipolar current-bypass electrical-circuit element (such as a pair of diodes opposingly coupled together in parallel) has: an impedance less than generally one-thousandth that of the coil portions; a first terminal coupled in parallel with the first and second coil portions; and a second terminal coupled in parallel with the third and fourth coil portions. A localized quench in one coil portion will be quickly shared with the other coil portions to reduce damage from the quench.
