ABSTRACT:
The invention relates to a process for the manufacture and adjustment of a Josephson effect magnetic flux pick-up. This process comprises depositing a thin, uniform layer (1) of a superconducting material on a cylindrical insulating bar (2) having an axis and a cylindrical surface, then making a cut (5) through the layer of superconducting material on a line along the cylindrical surface of the cylindrical bar (2), which line is parallel to the axis of the cylindrical bar, while leaving a bridge (7) between two edges of the layer of superconducting material defined by the cut, then subjecting the pickup thus manufactured to pulses for adjustment of the critical current, by induction, and in measuring, by induction, the parameters of the pick-up.
