Summary:The disclosed current lead (40) for supplying current to a superconducting device (26), such as a magnet coil, comprises an HTS conductor (11) extending along a length of the current lead and being thermally and electrically joined to an electrical shunt (21). Voltage taps (30, 32) are connected to respective ends of the HTS conductor for connection to a quench heater (34) which is in thermal contact with the superconducting device. A quench in the HTS conductor will give rise to a voltage appearing between the voltage taps, such voltage being applied to the quench heater to cause quench within the superconducting device, thereby providing a passive quench protection for the current lead.
