A winding arrangement for mitigating the effect of a quench of a superconducting coil has, a first electrical circuit A with a switch 41 and a persistent or non-persistent superconducting winding portion 31, and a second electrical circuit B with a normally conducting winding portion 32. The winding portions are magnetically coupled. When a quench is detected, the switch 41 is opened, current in the superconducting portion 31 is interrupted and inductively transferred to the ordinary conducting portion 32. The superconducting and normally conducting winding portions may be co-wound in adjacent, alternating layers, or a compound winding material may be used. A circuit dump resistor 44, 52 or diode 51 may be provided in the first or second circuits, to control and dissipate current. A switch may be provided in the second circuit B, to cause a forced quench of the superconducting winding portion. |
