N2 - We have measured the current-voltage (I-V) characteristics of a loop of four superconducting tunnel junctions at low temperatures (T≈50mK). In each branch of the loop, tunneling occurs through a small capacitance island (C∑≈1fF). In this geometry we can vary the magnetic flux Φ in the loop and the voltage Vg on gate electrodes, which have capacitance Cg to the small islands. We find that both Φ and Vg modulate the I-V curve.
