Abstract :
To assess the joint resistance between superconducting multifilamentary wires in a magnetic field, a measurement system using a current comparator has been developed for measuring the current decay induced in a superconducting loop containing a joint. It can measure both joint resistance and joint current carrying capacity up to 3000 A in a maximum magnetic field of 6.6 T. The joint resistances between superconducting wires soldered by diffusion welding and cold-pressing welding methods have been measured. The joint performance in magnetic fields of up to 6 T has been recorded
