Abstract

A new generation of Hall sensor magnetometer for non-destructive studies of superconductor homogeneity is proposed and tested. The magnetometer allows us to measure the threedimensional spatial dependence of all three components of magnetic field produced by applied or induced currents in the conductor. This new technique is more sensitive to detect small obstacles in (he current path than the old Hall sensor techniques measuring only the Field component perpendicular to the flat surface of the conductor. Having presented the measurement system, the method is demonstrated by experiments on multifilamentary BSCCO tapes.
