We have designed and tested an electronic circuit to record the amplitude of any current singularity in the current‐voltage characteristic of a Josephson tunnel junction. The detection of the peak current occurs only when the junction voltage is within a range that can be centered and narrowed conveniently. We describe the circuit in detail and illustrate its operation in the recording of some typical dc singularities.

Abstract
We have designed and tested an electronic circuit to record the amplitude of any current singularity in the current‐voltage characteristic of a Josephson tunnel junction. The detection of the peak current occurs only when the junction voltage is within a range that can be centered and narrowed conveniently. We describe the circuit in detail and illustrate its operation in the recording of some typical dc singularities.File in questo prodotto:
